Cu2AsAu
metal· JVASP-75716· Cu2AsAu
Cu₂AsAu is an intermetallic compound combining copper, arsenic, and gold in a defined stoichiometric ratio, belonging to the class of ternary metal systems. This material is primarily of research and specialized metallurgical interest rather than widespread industrial production, with potential applications in electronics, thermoelectric devices, and high-reliability contacts where the combination of noble metal (Au) stability and copper's conductivity offers advantages in extreme or precision environments.
