Global metallic phase change alloy market set for strong growth through 2035, driven by EV and data center demand
The global market for Metallic Phase Change Alloys (MPCAs) is on a sustained growth trajectory, with demand expanding at a compound annual rate of 6 to 9 percent through 2035, according to a market analysis published by IndexBox on June 25, 2026. The study covers the period from 2026 to 2035 and provides a comprehensive view of demand structure, supply dynamics, pricing, trade flows, and the competitive landscape for these specialized minor-metal alloys.Metallic Phase Change Alloys are engineered materials — typically formulated from indium, bismuth, tin, and gallium — that undergo solid-liquid phase transitions at precisely defined temperatures. Their substantially higher thermal conductivity compared to organic alternatives, ranging from 20 to 60 W per meter-kelvin, makes them indispensable in applications where heat flux density exceeds 50 W per square centimeter. The global market volume currently sits in the low thousands of tonnes annually.Electronics and data-center thermal management represents the largest end-use segment, accounting for 40 to 50 percent of total consumption. Industrial processing applications follow with a 25 to 35 percent share, while transportation — primarily lithium-ion battery thermal management for electric vehicles — accounts for 15 to 20 percent of demand. EV battery cooling is identified as the fastest-growing application, with its share of total consumption projected to increase by 5 to 8 percentage points by 2035.The connection to electric vehicle production is particularly significant. According to the IndexBox analysis, each 100 kWh of battery capacity uses an estimated 0.2 to 0.5 kg of alloy in pack-level thermal bridge design. With global EV battery production forecast to grow at 15 to 20 percent per year, alloy demand in this sub-segment alone is projected to increase at 12 to 16 percent annually. EV battery pack production is expected to grow from approximately 800 GWh globally in 2026 to an estimated 2,500 to 3,000 GWh by 2035, implying a near-tripling of alloy consumption in the transportation segment over the forecast horizon.In value terms, the market is projected to grow at a slightly lower CAGR of 5 to 7 percent, as standard-grade alloy prices face downward pressure from production scale and competition from non-metallic alternatives such as graphite pads and liquid cooling loops. The premium segment — covering high-purity alloys, custom ternary and quaternary compositions, and certified medical-grade material — is expanding significantly faster, at 10 to 13 percent annually. Premium high-purity grades with purity above 99.99 percent and melting-point tolerance of plus or minus 0.2 degrees Celsius command prices of USD 400 to 600 per kilogram, compared to USD 60 to 200 per kilogram for standard commercial grades.Supply concentration in China is identified as the most significant structural risk in the market. China accounts for an estimated 50 to 60 percent of global alloy production capacity and dominates upstream supply of key feedstocks: bismuth, a by-product of tungsten and copper mining, and indium, a by-product of zinc smelting. This creates structural import dependence exceeding 50 percent in both North America and Europe. The United States imports an estimated 30 to 40 percent of its MPCA requirements, while the European Union collectively imports 50 to 60 percent of its consumption.Input cost volatility for bismuth, indium, gallium, and tin is described as the single largest operational risk for alloy producers. Prices for these minor metals fluctuated by 25 to 40 percent over the 2022 to 2025 period, compressing margins for standard-grade producers and pushing procurement teams toward index-based contract pricing with reset periods of 3 to 6 months. Bismuth has historically traded between USD 4 and 8 per pound, while indium has ranged from USD 200 to 400 per kilogram. Bismuth and indium prices together account for 55 to 70 percent of standard-grade alloy cost.China's export controls on gallium and germanium, introduced in 2023, and more recent controls on indium have added further uncertainty to supply continuity, although enforcement on minor-metal alloy products has so far been less stringent than on pure metals. When Chinese domestic demand accelerates, the IndexBox analysis notes that spot prices in other regions tend to rise by 15 to 25 percent within two to three months.The supplier landscape is highly concentrated, with fewer than a dozen firms globally operating dedicated production lines for thermal management grades. Key producers identified in the report include Indium Corporation of the United States, AIM Solder of Canada, Honeywell Advanced Materials of the United States, and Chinese producers Yunnan Tin Group and Shenzhen Luvant Materials. The top three producers are estimated to hold 50 to 60 percent of global capacity for high-purity grades.Competition in the high-purity segment is intensifying as Chinese alloy producers upgrade their refining and quality-control capability, offering material at a 10 to 20 percent discount to Western producers while approaching equivalent specifications. OEMs and system integrators typically maintain two to three approved vendors per alloy chemistry, with supplier changes occurring only when qualification cycles open every 2 to 4 years or when price deviations exceed 15 percent over a trailing period.On the regulatory front, MPCA producers and traders face a tightening compliance environment. In the European Union, REACH regulations require safety data sheets and, for volumes exceeding one tonne per year, a chemical safety report. In the United States, the Toxic Substances Control Act applies to new alloy compositions. An emerging regulatory trend flagged in the report is the potential extension of conflict-mineral disclosure rules — under Dodd-Frank Section 1502 and the EU Conflict Minerals Regulation — to cover bismuth and indium, both of which can be by-products of mining in conflict-affected regions of Africa and Myanmar. This would substantially increase documentation burdens across the supply chain.Recycling infrastructure remains underdeveloped, with less than 5 percent of used thermal management material currently recovered for re-formulation. Firms that develop take-back and re-formulation services are identified as well-positioned to capture a captive source of low-cost feedstock while improving customers' ESG profiles, potentially at a cost premium of 15 to 20 percent over virgin material.Looking to 2035, North America and Europe are forecast to see slower volume growth of 3 to 5 percent per year but faster value growth of 6 to 8 percent annually, driven by their tilt toward premium certified alloys. Southeast Asia and India are projected to gain 3 to 5 percentage points of global consumption share as semiconductor packaging and server assembly activity expands in those regions. The key downside risk to the forecast is the pace of substitution by graphene-based and ceramic thermal interface materials; if these alternatives reach cost parity with metallic alloys for heat fluxes below 150 W per square centimeter, market growth could be capped 1 to 2 percentage points below the baseline projection.Source: IndexBox, World Metallic Phase Change Alloy — Market Analysis, Forecast, Size, Trends and Insights, updated June 25, 2026.
Gold breaks below $4,000 as stronger dollar and post-Fed repricing deepen selloff; silver plunges 6.5%
Spot gold and silver prices fell sharply on Wednesday, with gold breaching the psychologically significant $4,000 level as a combination of a firmer U.S. dollar, post-Federal Reserve rate repricing, and easing geopolitical tensions in the Strait of Hormuz overwhelmed residual safe-haven demand linked to the U.S.-Iran situation.At the time of writing, spot gold was trading near $3,998.00 per ounce, down 2.73% on the session, while spot silver tumbled to approximately $57.470, a decline of 6.50%, bearing the brunt of the day's selling pressure, according to Kitco News.The primary driver of the selloff remains the Federal Reserve's policy stance. The Fed held the target range for the federal funds rate at 3.50% to 3.75% at its June 17 meeting, but its statement maintained a firm focus on elevated inflation and delivered a direct price-stability signal. Post-meeting market positioning has shifted decisively toward a higher-for-longer rate environment, keeping the U.S. dollar well supported, front-end rate risk elevated, and non-yielding assets such as gold under pressure. Gold futures settled the session at their lowest level since November, while bitcoin and silver also weakened as rate-sensitive selling hit hard assets and cryptocurrencies alike.Geopolitical developments in the Middle East added another layer of downward pressure on gold. The Strait of Hormuz, which under normal conditions handles approximately one-fifth of global crude oil flows, has shifted from an outright closure risk scenario to what market participants are characterizing as a fragile reopening trade, following a U.S.-Iran memorandum of understanding. Limited shipping transits have resumed, reducing the immediate oil-supply shock premium and pulling Brent crude prices back toward the mid-$70s range. The easing of inflation fears tied to energy supply disruptions has consequently weakened gold's haven appeal at a moment when dollar strength and Fed policy are already applying significant downside pressure.Cross-asset markets broadly reflected the de-escalation trade. Brent crude fell 3.8% to $73.87 a barrel, while the yield on the 10-year U.S. Treasury note declined to 4.41%. U.S. equities finished mixed, with the S&P 500 edging down 0.1%, the Nasdaq Composite falling 0.4%, and the Dow Jones Industrial Average posting a modest gain of 0.4%. Jim Krane, energy research fellow at Rice University's Baker Institute, cautioned that lower crude prices do not signal a fully normalized physical market, noting that stocks are running low.From a technical perspective, market analyst Muhammad Umair, cited by Kitco News, identified the $3,950 to $4,000 range as the critical support zone for spot gold. A failure to hold that zone would expose the next downside target at $3,850. On the upside, bulls must reclaim the $4,350 resistance region, with a sustained move above that level targeting $4,500. First resistance is seen at $4,000 and then at $4,350, while first support is located at $3,950, followed by $3,850.For silver, the technical picture is equally challenged. The bears' next downside price objective is a break below $55.00, with deeper targets in the $45.00 to $55.00 accumulation zone. Bulls, by contrast, would need to drive prices back above the $70.00 to $72.00 area, with a move beyond that zone targeting $78.60. First resistance is seen at $60.00 and then $72.00, while next support is identified at $55.00 and then $45.00.Source: Kitco NewsWire / Kitco News (kitco.com), June 24, 2026.
Brimstone and Century Aluminum sign MoU to build first fully domestic US aluminium supply chain
Brimstone and Century Aluminum have entered into a memorandum of understanding (MoU) with the stated goal of establishing a fully domestic "mine to metal" supply chain for primary aluminium production in the United States, according to a report by Mining Technology dated June 25, 2026.Under the terms of the agreement, Brimstone will supply Century Aluminum with significant volumes of alumina — the critical intermediate product used in aluminium smelting — sourced from its planned US-based production facility. The partnership is designed to anchor what the companies describe as the first aluminium supply chain entirely sourced and produced within the United States.The MoU addresses a well-documented structural vulnerability in the American aluminium industry. The US currently lacks economically viable domestic bauxite deposits, forcing producers to rely on imported raw materials. This dependency is compounded by the fact that China accounts for approximately 60% of global production of both alumina and aluminium, while the US produces less than one-sixth of the aluminium it consumes domestically.Brimstone CEO Cody Finke highlighted the strategic significance of the deal, stating: "Foreign sources, including China, currently dominate global alumina production. Brimstone is bringing alumina production home and doing it at a globally competitive price. Brimstone is upending the massive global imbalance by producing alumina from rock quarried here in the US."Brimstone's technology is notably distinct from conventional alumina production, which depends on bauxite ore. The company is developing a process to extract alumina from common rock quarried domestically in the US, a potential breakthrough for a country that has historically had no economically viable bauxite resources.The company's demonstration plant in Reno, Nevada, is scheduled to begin operations in 2028. The first industrial-scale facility is targeted for completion by 2034, with an expected annual production capacity of approximately 350,000 tonnes of smelter-grade alumina.The partnership with Century Aluminum is intended to provide an offtake anchor that supports the development of Brimstone's industrial-scale plant. Beyond alumina supply, the MoU is framed as a measure to bolster supply chain resilience and reduce US dependence on imports, which the companies note can be exposed to international disruptions.Century Aluminum has been actively expanding its domestic footprint. In April 2026, the company restarted idle capacity at its Mt. Holly facility in South Carolina, representing a $50 million investment. The company also recently announced a joint venture with Emirates Global Aluminum to construct a primary aluminium production plant in Inola, Oklahoma.Brimstone, meanwhile, is broadening its industrial ambitions beyond aluminium. The company confirmed it is in discussions with additional customers and partners, with its portfolio expanding to include potential applications in cement, steel, and other critical minerals sectors.The announcement reflects a broader strategic push within the United States to reduce reliance on foreign-controlled critical mineral supply chains, particularly in materials deemed essential to national security and industrial competitiveness.Source: Mining Technology, June 25, 2026.
Kaiser Reef launches diamond drilling campaign at Maldon Gold Project in Victoria
Kaiser Reef (ASX: KAU) has commenced surface diamond drilling at the Maldon Gold Project in Victoria, initiating an exploration program targeting four separate prospects across an initial 4,350-metre campaign, according to a report published by Mining.com.au on June 24, 2026.The company has begun drilling operations at the Quill gold target, a prospect identified through tailings storage facility sterilisation drilling combined with follow-up resistivity surveys. Previous drilling at the Quill target returned encouraging results, with hole TSAC_021 intersecting 8 metres at 4.16 grams per tonne gold from 10 metres depth, including a higher-grade interval of 2 metres at 9.90 grams per tonne gold from 11 metres.The surface program is designed to progress sequentially through three additional targets. Union Hill North is set to test northern extensions to Eaglehawk Reef mineralisation, ahead of planned underground drilling activities. The Nuggetty South target is intended to test 170 metres of untested strike between areas of known mineralisation along a newly interpreted shallow plunge corridor. Historical drilling results along this plunge zone have returned 3.4 metres at 34.0 grams per tonne gold and 4.3 metres at 11.2 grams per tonne gold, underscoring the high-grade nature of the system. The program will additionally target the Nuggetty west lode and various remnant targets.Managing Director Brad Valiukas described Maldon as remaining substantially underexplored, despite the project area having historically produced 1.75 million ounces at an average grade of 28 grams per tonne gold — a figure that underlines the exceptional geological endowment of the district."We see a long and continuing pipeline of surface exploration opportunity and expect to maintain a surface rig for the long term, complementing underground activity at the Union Hill Gold Mine," Valiukas stated, as quoted by Mining.com.au.The Quill target emerged from Kaiser Reef's recently completed aircore drilling program at the proposed tailings storage facility location. A reconnaissance resistivity survey subsequently identified a high-resistivity zone trending north-south, coincident with the TSAC_021 intersection, which geologists have interpreted as a potential quartz reef structure.Kaiser Reef expects drilling activities to continue throughout 2026, with additional surface targets currently being developed from geological mapping, soil sampling programs, and an upcoming helicopter-borne magnetic survey designed to refine structural understanding of the project area.Beyond Maldon, Kaiser Reef also operates the Henty Gold Mine in Tasmania, which carries a 199,000-ounce gold ore reserve and targets annual production of approximately 30,000 ounces. The Maldon Gold Project itself benefits from a fully permitted 200,000-tonne-per-annum processing facility and existing underground access infrastructure, positioning the project for a potentially accelerated development pathway should exploration drilling confirm the presence of additional economic mineralisation.Source: Mining.com.au, authored by JC Villarba, published June 24, 2026.
Congo pivots westward as cobalt export controls reshape supply chains
The Democratic Republic of Congo is leveraging its dominant position as the world's largest cobalt producer to pursue a sweeping geopolitical realignment, using export restrictions to simultaneously reshape global supply dynamics and reduce its dependence on Chinese operators in favor of closer ties with Western nations, particularly the United States.Kinshasa has been restricting cobalt exports since February 2025, initially through a full ban before transitioning to a quota system introduced in October of that year, according to Reuters columnist Andy Home. Shipments only began picking up again in early 2026, hampered by administrative challenges associated with implementing the new quota framework.The impact on China, the dominant buyer of Congolese cobalt, has been dramatic. According to data from the World Bureau of Metal Statistics, which collates customs information, China imported just 5,000 metric tons of Congolese cobalt between January and April 2026, compared to almost 200,000 tons during the same period in 2025. The figures underscore the effectiveness of Kinshasa's export controls in redirecting — or withholding — supply from traditional trade channels.Cobalt is a critical material used across a wide range of strategic applications, from consumer electronics such as mobile phones to advanced defense technologies including stealth bombers. Its role in the global supply chain for battery technology and military hardware makes it a commodity of significant geopolitical weight.As it asserts greater control over its cobalt sector, the DRC government is simultaneously attempting to integrate artisanal and small-scale mining operations into the formal economy. This effort represents both an economic and ethical challenge, as Western cobalt buyers have long flagged concerns over labor conditions and supply chain transparency in the artisanal mining sector in Congo.The DRC's pivot toward the West marks a notable shift in the country's strategic posture, occurring against a backdrop of intensifying global competition for critical minerals. Western governments and corporations, seeking to reduce their own dependence on Chinese-controlled supply chains for battery materials and other strategic inputs, may find Kinshasa's overtures aligned with their own supply security objectives.The full implications of Congo's rebalancing strategy — and the extent to which Western partners will engage — remain to be seen, but the early data suggests the export quota system is already producing measurable disruption in established cobalt trade flows.Source: Reuters / Mining.com, June 24, 2026.
GECF Secretary General: global natural gas markets set to stabilize in Q3 as Strait of Hormuz reopens
Global natural gas markets are on track to stabilize during the third quarter of 2026, following the reopening of the Strait of Hormuz in the wake of a ceasefire between the United States and Iran, according to Philip Mshelbila, Secretary General of the Gas Exporting Countries Forum (GECF).Mshelbila made the remarks on Wednesday at the Reuters Global Energy Forum in New York. "If we assume that the Strait (of Hormuz) is now open and will remain open, our view is actually that in the course of this next quarter we will begin to see some re-stabilization in the market," he said.The GECF chief also expects both export flows and prices to revert closer to pre-conflict levels in the fourth quarter, though Asian prices may remain elevated in the short term.The conflict in Iran, which began when the United States and Israel launched strikes on February 28, severely disrupted oil and gas exports from major Middle Eastern suppliers, pushing global energy prices to their highest levels in years. In response, governments worldwide moved to shield consumers from soaring energy costs by tapping strategic reserves and urging businesses and households to conserve energy. Gas prices in Europe and Asia surged to their highest level in March 2026 since the 2022-2023 crisis triggered by Russia's invasion of Ukraine.The GECF represents some of the world's leading gas-exporting nations, including Algeria, Bolivia, Egypt, Equatorial Guinea, Iran, Libya, Nigeria, Qatar, Russia, Trinidad and Tobago, the United Arab Emirates and Venezuela. Together, its members account for approximately 70% of the world's proven gas resources.Prior to the conflict, most analysts had projected that global gas supply and demand would continue reaching record highs over the next decade, driven largely by Asian countries transitioning from coal to gas-fired power generation.On the outlook for China, Mshelbila expressed confidence that the country's LNG demand will continue to grow, despite its efforts to diversify energy supplies through expanded renewable capacity, pipeline gas imports from Russia, and increased domestic production. "Coal to gas switching is going to continue, and we do believe that the growth in the LNG demand of China will continue to grow," he said.The United States remains the world's largest LNG exporter, followed by Qatar and Australia. However, Mshelbila noted that several African nations are likely to emerge as significant LNG producers in the coming years, which could exert downward pressure on prices.On regulatory matters, the GECF Secretary General urged the European Union to delay the introduction of new methane emission rules that could penalize LNG imports, pending the development of globally coordinated standards. While acknowledging that environmental protection should be a priority, Mshelbila argued that Europe cannot unilaterally set rules for the rest of the world. "You cannot isolate Europe as though it existed in its own climate bubble. It doesn't. While you could limit what comes into Europe, whatever Europe is not buying is going to go somewhere else. It's going to be burnt somewhere else...We have one atmosphere, one planet," he said.The GECF called for suspending current regulatory timelines and engaging in a broader dialogue to develop realistic climate regulations applicable on a global scale.Source: Reuters, reporting by Curtis Williams in Houston; editing by Nathan Crooks and Sanjeev Miglani.
