America Is Stockpiling Tungsten. Who Actually Depends on It?

That distinction matters after the U.S. government dramatically expanded its tungsten security effort. On September 14, 2026, Elmet Group announced that its Elmet Technologies subsidiary had received an indefinite delivery, indefinite quantity contract from the Defense Logistics Agency to supply tungsten ores, concentrates and sodium tungstate for the National Defense Stockpile. The contract has a ceiling of up to $2 billion, but only $150 million is a guaranteed funded commitment. Separately, Elmet announced a $450 million committed government investment intended to expand U.S. manufacturing, processing and allied-country sourcing.

The structure is more important than the headline number. Elmet says it does not intend to begin delivering tungsten into the stockpile until incremental supply becomes available from new mining investments, offtake agreements and processing expansions. In other words, the government is trying to build inventory without immediately competing with American manufacturers for the same constrained material.

That makes the policy less of a short-term demand shock than a financing mechanism for a different tungsten supply chain. For investors, the more useful question is therefore not simply which companies "use tungsten." It is where a change in tungsten availability or price can become large enough to affect working capital, margins, production or project economics.

The biggest industrial dependency is carbide tooling

Tungsten's largest U.S. application is much less exotic than missiles or advanced chips. The U.S. Geological Survey estimates that roughly 60 percent of tungsten consumed in the United States goes into cemented carbide parts used for cutting and wear resistance, particularly in metalworking, construction, mining and oil and gas drilling. The United States has not commercially mined tungsten since 2015, while net import reliance remained above 50 percent in 2025.

This is the first place investors should look for measurable dependence because tungsten carbide is not an incidental material for a cutting-tool producer. It is part of the product itself.

Kennametal provides an unusually clear example. The company identifies tungsten ore concentrates and scrap carbide as major metallurgical raw materials and explicitly warns that the concentration of tungsten mining and processing in China, together with export controls, has increased uncertainty around both availability and cost. Kennametal uses long-term supply agreements, spot purchases and internal tungsten recycling to manage that risk.

The financial statements show how large the effect can become. Kennametal said rising tungsten prices were responsible for a $570.2 million increase in inventories during fiscal 2026. Its operating cash flow went from positive $208.3 million in fiscal 2025 to negative $4.0 million in fiscal 2026, with the inventory build associated with tungsten prices a major contributor. At the same time, favorable timing between raw-material-related pricing and costs contributed approximately $316 million to fiscal 2026 operating income.

That is the important investment mechanism. Rising tungsten prices are not automatically bad for a tooling manufacturer. If selling prices adjust faster than the company's accounting cost of inventory, reported margins can temporarily expand. Yet the same move can consume enormous amounts of cash as more working capital becomes trapped in higher-value inventory. If tungsten prices later fall, pricing and inventory economics can change again.

Kennametal therefore illustrates a more useful definition of commodity exposure than simply asking whether tungsten appears in a company's products. Tungsten can materially change both its income statement and balance-sheet requirements.

Sandvik shows a related but somewhat different profile. In its fourth-quarter 2025 reporting, the Swedish industrial group said global scarcity of tungsten powder had produced stronger demand and higher prices, while pricing in its Chinese cutting-tools business was strongly correlated with tungsten prices. Sandvik also pointed to its own mining and processing capabilities as an advantage during the shortage.

This makes vertical integration and recycling strategically important. Two companies may sell similar carbide tools but have different economic exposure if one can recover tungsten from used tools or control more upstream material. The investment question is not merely who consumes tungsten, but who has to purchase incremental tungsten from the market when supply tightens.

China matters even when the tungsten was not imported directly from China

The United States' direct reliance on Chinese tungsten can understate the actual supply-chain problem.

USGS estimated that imports from China accounted for about 14 percent of U.S. apparent tungsten consumption on average from 2020 through 2023, while total U.S. net import reliance was about 50 percent in 2024. That does not look like extreme direct dependence. Globally, however, China dominates tungsten mining, processing and consumption, which means non-Chinese suppliers still operate inside a market whose marginal availability and price can be heavily influenced by Chinese policy.

China made that influence more visible in February 2025 when the Ministry of Commerce and General Administration of Customs imposed export controls covering products including ammonium paratungstate, tungsten oxide and tungsten carbide, as well as certain high-tungsten solid materials and alloys. Chinese authorities described the controlled items as having both civilian and military uses.

USGS subsequently reported a sharp rise in 2025 tungsten prices. Rotterdam prices for 65 percent tungsten concentrate increased from $266 to $551 per metric ton unit during the year, while ammonium paratungstate increased from $331 to $675.

The Kennametal results show why that matters even to a U.S. manufacturer that is not simply importing every pound of tungsten from China. A globally constrained intermediate material reprices inventories, alternative feedstock, recycled material and long-term contracts throughout the chain.

This also explains the logic behind the new stockpile program. The strategic vulnerability is not just the national origin printed on a shipment entering a U.S. port. It is insufficient mine output, conversion capacity and intermediate processing outside a highly concentrated global system.

Defense needs tungsten, but the dependency sits below the prime contractors

Tungsten has obvious military applications. Its high density, hardness and temperature resistance make it useful in penetrators, fragmentation products, counterweights, high-temperature components and other demanding systems. USGS specifically identifies tungsten heavy alloys for armaments and tungsten-bearing materials for high-temperature applications.

But this does not mean a major defense prime should be treated as a tungsten stock.

The more direct exposure sits with specialized material and component companies several layers below the finished missile, aircraft or weapons system. Elmet is one example. For the six months ended July 3, 2026, Aerospace, Defense and Government customers accounted for 39.9 percent of Elmet's revenue. The company said growth came partly from programs including Javelin, Hellfire and Next Generation Interceptor and from favorable tungsten pricing.

Even there, the exposure has to be interpreted carefully. Tungsten represented 18.7 percent of Elmet's shipment composition over the same six-month period, while molybdenum represented 59.4 percent. The company specifically attributed much of its Javelin and Hellfire volume growth to molybdenum products. A defense program appearing in Elmet's backlog therefore does not prove that the program is proportionately dependent on tungsten.

That is an important limitation when tracing critical minerals through defense supply chains. The strategic importance of a material can be very high even when its dollar share of a prime contractor's cost base is very small. A shortage of a specialized tungsten component could delay production, but that does not make tungsten prices a meaningful direct driver of the prime contractor's consolidated margins.

The investment sensitivity is more concentrated upstream, where processors must source, finance and manufacture tungsten-containing materials themselves. This is one reason the government's current strategy is aimed at mining, conversion and specialized manufacturing rather than simply subsidizing the final defense companies that buy finished components.

Semiconductor exposure is about WF6 and process availability, not bulk tonnage

Tungsten's role in semiconductors is even easier to misinterpret.

Chip fabrication does use tungsten in important structures. Applied Materials says tungsten has long been used in logic contacts, middle-of-line connections and metal gate fill because of its electrical properties and ability to fill very small structures. Its Endura Volta systems deposit tungsten into semiconductor contacts, including selective tungsten processes that fill contact vias without conventional liner and nucleation layers.

But fabs are not consuming tungsten on the same physical scale as carbide tooling companies. Semiconductor dependence occurs through highly processed materials and chemistry.

One important intermediate is tungsten hexafluoride, or WF6, a specialty gas used as an ALD and CVD precursor for tungsten deposition. Kanto Denka Kogyo, a Tokyo Stock Exchange listed specialty chemical producer with securities code 4047, explicitly lists WF6 among its semiconductor specialty gases and identifies it as an ALD and CVD precursor.

That shifts the semiconductor investment question. For a chipmaker, the risk is not that a doubling of bulk tungsten prices necessarily produces a comparable increase in wafer cost. Tungsten represents only one material inside an extraordinarily high-value fabrication process. What matters more operationally is whether specialty-gas suppliers can continue converting tungsten into the purity and chemical form required by deposition processes.

There is also a substitution caveat. Applied Materials continues to support tungsten deposition, but its current contact-metal roadmap also includes molybdenum-based processes as device structures continue to shrink. Tungsten is therefore important to semiconductor manufacturing without being technically permanent in every application or node.

For investors trying to identify semiconductor exposure, a specialty chemical producer such as Kanto Denka sits closer to the tungsten bottleneck than a diversified chipmaker. Applied Materials is relevant because it supplies tungsten deposition equipment, but its economics are linked to semiconductor equipment spending and process adoption rather than simply to the market price of tungsten.

The stockpile deal could matter most to smaller upstream suppliers

The other side of a supply shortage is the value of creating new supply.

Elmet's September plan directs government-backed capital across mining, processing and manufacturing rather than toward stockpiling alone. The company says it expects to allocate approximately $150 million to the Springer Tungsten Complex in Nevada, where it plans to form a majority-owned processing joint venture with Blue Moon Metals and EQ Resources. Elmet currently expects the Springer mine and mill to restart production in the fourth quarter of 2027 and the associated ammonium paratungstate conversion facility to begin operating in the second half of 2028. Those dates remain company targets rather than operating assets already in production.

Blue Moon Metals, listed on Nasdaq as BMM and on the TSX Venture Exchange as MOON, is advancing the Springer project. The site already contains historical mine and processing infrastructure, including an APT circuit, but Blue Moon is still conducting drilling, resource work and redevelopment. Historical resource figures associated with the property should not be treated as current mineral resources unless and until they are verified under applicable reporting standards.

EQ Resources adds existing allied-country mine exposure through tungsten operations associated with Australia and Spain, which Elmet has identified as part of its intended supplier network. The broader plan is to connect those sources with U.S. conversion and manufacturing capacity.

For these smaller companies, the government program changes the analysis more directly than it does for a diversified defense prime. Capital commitments, processing investment and visible government demand can improve the commercial case for projects that previously had to compete against a tungsten market dominated by Chinese supply. They do not remove geological, construction, financing or operating risk, but they can change which projects are economically worth attempting.

Elmet itself is also changing. Historically, it has been a specialized downstream manufacturer rather than a conventional mining company. Its new strategy adds sourcing, refining and trading functions on top of that manufacturing base. If executed, the company will sit at several stages of the Western tungsten chain rather than at only one.

That makes the $2 billion stockpile ceiling less important as a near-term revenue estimate than as evidence of the structure the U.S. government is attempting to create. The funded minimum and the separate manufacturing investment provide demand visibility and capital while Elmet builds or connects new supply.

The investment conclusion

The new U.S. stockpile agreement is therefore most significant as an attempt to change the supply side. Because Elmet plans to delay stockpile deliveries until new material becomes available, the program is not designed to take $2 billion of tungsten out of today's commercial market. It is designed to help create mines, processing capacity and supplier networks that can eventually support both government inventories and industrial customers.

For investors, that produces a useful hierarchy of tungsten exposure. Tooling companies reveal the commodity in working capital and pricing. Specialized processors reveal it in manufacturing volumes and margins. Small miners and developers reveal it in project economics. Defense primes and semiconductor manufacturers sit farther downstream, where tungsten may be technically important without being a large disclosed cost item.

That is why the clearest public-company tungsten dependencies are several layers removed from the companies most commonly associated with national security and advanced technology. The critical mineral is important precisely because a relatively small upstream market feeds much larger industries that cannot always substitute away from it quickly.
