The battle in Iran is fueling U.S. chatter about restoring the home manufacturing of tungsten—a supermetal essential to the protection business.
Tungsten, which is broadly utilized in munitions, reportedly together with in Tomahawk missiles, has develop into exceedingly scarce since China, the main world producer, put export restrictions on it in 2025. U.S. firms stopped mining tungsten in 2015 when the price of importing it undercut home manufacturing prices. However the scarcity has spurred some firms to start exploring U.S. manufacturing once more.
Tungsten is famend for its hardiness. Of all the weather on the periodic desk, tungsten, first remoted in 1783, has the very best melting level (6,192 levels Fahrenheit) and boiling level (10,706 levels F, concerning the temperature of the solar’s floor). It has the very best tensile power of all metals and is denser than lead, making it extremely fascinating for armor-piercing and bunker-busting munitions.

In 2025 China produced greater than 78 p.c of the worldwide provide of tungsten, which was practically 94,000 tons worldwide, in line with a report from the U.S. Geological Survey launched earlier this yr. With the export restrictions, the price of tungsten ore has steadily elevated globally since early 2025. Within the U.S., the price of importing tungsten has elevated steadily since 2018, however in latest months the worth has had a pointy decline, in line with a Scientific American evaluation of knowledge compiled by BusinessAnalytiq.
On February 27, in response to the scarcity of tungsten and different metals, the Pentagon despatched a letter to a bunch of greater than 1,500 firms and educational establishments that work with the U.S. army, urging them to extend home manufacturing, in line with Reuters. The following day, the U.S. launched its first strikes in opposition to Iran.
4 weeks later the U.S. had fired greater than 850 Tomahawk missiles—greater than 9 instances the quantity the Division of Protection normally procures in a yr—in line with the Washington Put up. The U.S. has additionally used not less than 40 of its estimated 90 “Precision Strike Missiles,” in line with an April report from the Middle for Strategic and Worldwide Research. These missiles are designed to blow up in midair, spraying greater than 180,000 tungsten pellets outward. On the finish of March, the New York Instances reported that these missiles had been detonated above civilian areas within the Iranian metropolis of Lamerd in February.
With the renewed strikes in Iran, the variety of these kind of weapons used is more likely to develop—NBC Information reported that leaders within the protection business plan to fulfill this week with the White Home about its dwindling provide of missiles.
The U.S. has important deposits of tungsten throughout the western elements of the nation, in line with a USGS report. Other than its use in weapons, it is a perfect steel for reducing and drilling devices like saws and bits.
“Your common building of any form of infrastructure could be near unattainable with out utilizing tungsten, tungsten carbide or tungsten-tipped instruments,” says Ali Haji, CEO of American Tungsten.
Haji says that when the tungsten ore is mined, it’s normally processed right into a focus and shipped to a processor that turns it into ammonium paratungstate, or APT. Then the APT is heated to a excessive temperature in a course of referred to as calcination and subsequently lowered with hydrogen to provide the tungsten powder that’s bought to producers and different finish customers.
American Tungsten hopes to have its Idaho mine website producing the steel by 2027. Haji says he ultimately hopes the mine will provide 8 p.c of the U.S. demand for tungsten. In February the corporate introduced the outcomes of an preliminary exploration of the positioning that steered it contained giant portions of each tungsten trioxide and silver.
In contrast to different exhausting metals, tungsten is essentially unhazardous, however the byproducts from mining it—referred to as tailings—include different dangerous metals together with arsenic, copper, zinc and lead and may leach into the atmosphere. Haji says their mine avoids these points by drilling above the water stage.
“We’ve acquired no discharge popping out from the positioning, and the grades are, usually talking, thrice greater than the worldwide common that’s in manufacturing immediately,” Haji says.
Almonty Industries, a world mining firm, introduced it had bought a tungsten mine in Montana final yr and, earlier this yr, relocated its headquarters from Toronto to the state.
The U.S. authorities has additionally begun to spend money on home tungsten manufacturing tasks. In January of final yr, the Division of Power introduced it was giving Texas-based MELT Applied sciences greater than $5.7 million to provide tungsten carbide. And the Division of Protection introduced a $6.2-million grant to Guardian Steel Assets final yr to conduct a prefeasibility examine on a mine in Nevada. Neither firm responded to requests for remark from Scientific American.
“Growing a home supply for tungsten is certainly one of our high essential and strategic mineral priorities,” Vic Ramdass, the Protection Division’s performing assistant secretary of protection for industrial base coverage, stated in a press launch asserting the 2025 grant to Guardian Steel Assets.
Not too long ago scientists have been experimenting with tungsten for a unique function—as shielding nuclear fusion reactors. In 2024 French and American scientists have been capable of include plasma at 50 million levels Celsius for six minutes by utilizing a fusion machine referred to as a tokamak clad in tungsten as a substitute of the normal graphite tiles. However working with it may be difficult, stated Luis Delgado-Aparicio, the top of superior tasks at Princeton’s Plasma Physics Laboratory, in a press launch. “That is, merely, the distinction between attempting to seize your kitten at house versus attempting to pet the wildest lion.”
As tungsten provides stay scarce, U.S. industries are adjusting to the availability subject. Drill bit makers who serve the oil and fuel business are changing tungsten drill bits with metal, which wears extra shortly.
Haji says he hopes the U.S. authorities will assist defend the nascent home suppliers of the essential supermetal.
“I believe a few of that duty falls upon the federal government to place some form of worth safety in place, ought to the Chinese language flood the market once more,” he says.
“Firms equivalent to ourselves have deployed a number of capital to deliver North American manufacturing on-line.”
