· CoCu2Sn

CoCu₂Sn is an intermetallic compound combining cobalt, copper, and tin in a defined stoichiometric ratio, belonging to the family of ternary metallic intermetallics. This material exhibits high stiffness and density, making it potentially valuable in applications requiring structural rigidity and wear resistance, though it remains primarily a research or specialized-use compound rather than a commodity alloy. Industrial applications are limited but emerging in wear-resistant coatings, electrical contacts, and high-performance composite reinforcement where the material's hard, brittle nature and thermal stability can be leveraged.
