· JVASP-21716· As3W2

As₃W₂ is an intermetallic compound combining arsenic and tungsten, representing a brittle metallic phase that forms in the As-W binary system. This material is primarily of research and industrial interest in high-temperature applications and specialized alloy development, where its thermal stability and density make it relevant for refractory or wear-resistant compositions. Engineers may encounter As₃W₂ as a constituent phase in tungsten-based alloys or in studies of heavy-metal intermetallics, though direct engineering use remains limited compared to conventional tungsten alloys or superalloys.
