· JVASP-40498· Sc2CuAu

Sc2CuAu is an intermetallic compound combining scandium, copper, and gold in a fixed stoichiometric ratio. This material belongs to the family of ternary metallic intermetallics, which are primarily of research interest rather than established industrial commodities. Intermetallics in this composition range are investigated for potential applications requiring combinations of high stiffness, low density, and thermal stability, though Sc2CuAu itself remains largely experimental; engineers encounter similar compounds in aerospace and specialty electronics contexts where weight reduction and extreme-environment performance justify material development costs.
