· JVASP-63330· ErCu4Au

ErCu4Au is a ternary intermetallic compound combining erbium, copper, and gold, belonging to the family of rare-earth metallic systems. This material is primarily of research interest rather than established industrial production, with potential applications in high-density electronic contacts, thermoelectric devices, and specialized alloy development where rare-earth strengthening and precious metal properties are simultaneously desired.
