CrAu4 is an intermetallic compound composed of chromium and gold in a 1:4 atomic ratio, belonging to the family of gold-based metallic intermetallics. This material is primarily of research and specialized industrial interest rather than a commodity alloy, valued in applications requiring the combined properties of gold's chemical inertness and corrosion resistance with chromium's hardening and wear-resistance contributions. Its notable characteristics—including high density and stiffness—make it a candidate for precision applications where chemical stability and mechanical performance are both critical, though its cost and limited commercial availability restrict adoption compared to conventional alloys.
