Elmet Technologies VerifiedAS9100
Described as the last and only fully integrated US-based producer of tungsten and molybdenum products. Melt origin is recorded as not-applicable because this is a powder metallurgy route: doped powder is pressed, sintered and worked to fully dense product, and nothing is melted. Do not read DFARS 252.225-7009 specialty metals onto this. For tungsten the governing restriction is 10 U.S.C. 4872, which bars metal melted OR PRODUCED in China, Russia, North Korea or Iran, so the question to ask is where the powder came from. Elmet is US-owned and operated, but the US has essentially no tungsten mine production, and powder origin is not published. Confirm it per lot.

Global Tungsten & Powders Reported
Gold-plated wire is a named product. Whether the substrate is tungsten is not stated explicitly, though tungsten wire is GTP's usual base; confirm before relying on it.
