ZnAu3 is an intermetallic compound composed of zinc and gold in a 1:3 atomic ratio, belonging to the family of precious metal intermetallics. This material combines gold's corrosion resistance and chemical inertness with zinc's lower cost, resulting in a hard, brittle metallic phase typically investigated for specialized applications where wear resistance and thermal stability are prioritized. While not widely used in high-volume production, ZnAu3 and similar gold-zinc phases appear in research contexts for electrical contacts, decorative coatings, and brazing alloy development, where the material's high density and stiffness can be leveraged despite limited ductility.
