CuAu3 is an intermetallic compound in the copper-gold system, characterized by a fixed stoichiometric ratio of one copper atom to three gold atoms. This material belongs to the ordered intermetallic family and exhibits enhanced hardness and ordered crystal structure compared to random solid solutions, making it relevant for applications where both strength and gold's corrosion resistance are valued. While not commonly found in high-volume industrial production, CuAu3 appears primarily in specialized applications and research contexts where its unique combination of metallic bonding, thermal stability, and resistance to degradation justify the material and processing costs.
