Ta3W
metal· JVASP-102564· Ta3W
Ta3W is a tantalum-tungsten intermetallic compound combining two refractory metals with exceptionally high melting points and density. This material is primarily of research and specialized industrial interest, valued in ultra-high-temperature applications where thermal stability, oxidation resistance, and structural integrity must be maintained at extreme conditions where conventional superalloys fail.
