Foundation Alloy designs and manufactures advanced engineering alloys using MetalsFIRST, a proprietary solid-state process that makes metal parts from powder without ever melting the metal. Because composition is not constrained by melt chemistry, the company can design alloys for performance and reach grain structures roughly 100x finer than conventionally processed metals, with strength, ductility and thermal stability achieved as-sintered. Its first commercial line is molybdenum alloys - MC700 and the higher-strength MC1200 - with an MC-X grade and specialty steels announced as coming. The technology originated as solid-state metallurgy research at MIT and UC Irvine; the company was founded in 2022, is headquartered in Cambridge, Massachusetts, manufactures domestically, and raised a $10.5M round.
