Helix Build

Magnesium is a designated critical material — the lightest structural metal, essential to automotive lightweighting, aerospace, defense alloys, and as a reducing agent in titanium and rare-earth production. Global demand is estimated near 20.8 million tons in 2026, with the metal market projected to nearly double by 2033, yet U.S. primary capacity has contracted to a single producer serving a fraction of demand.

The supply risk is acute and concentrated. China produces roughly 85% of the world’s magnesium and has repeatedly used export licensing as leverage, alongside restrictions on gallium, germanium, and antimony. For U.S. automakers, defense primes, and aerospace OEMs, a licensable single-country dependency on a structural input is exactly the vulnerability current industrial policy is designed to eliminate.

There is currently no fully integrated U.S. magnesium platform spanning feedstock through qualification-grade finished product. Qualification cycles are long and sticky — once a producer is designed into an alloy or a defense specification, that relationship endures for years. First movers who control feedstock and reach qualification will set domestic pricing and capture multi-year OEM and Department of Defense contracts.

The tailwinds are aligned: Defense Production Act Title III support for domestic magnesium has been greenlit, domestic-content and friend-shoring rules are tightening across autos and defense, and strategic-stockpile interest is returning. The platform is built vertically — feedstock control, primary production and alloying, downstream manufacturing, and integrated logistics — to capture that policy-created margin end to end.
