· JVASP-79607· CrInCu2

CrInCu₂ is a ternary intermetallic compound combining chromium, indium, and copper in a defined stoichiometric ratio. This material belongs to the family of metallic intermetallics, which are ordered compounds that can offer enhanced hardness, thermal stability, and corrosion resistance compared to conventional single-element metals or simple binary alloys. Research on CrInCu₂-type compositions is primarily driven by interest in advanced functional materials and potential applications requiring combinations of electrical conductivity and mechanical strength; such ternary systems are studied for their phase stability and potential use in specialized high-performance environments, though industrial adoption remains limited compared to established alloys.
