CrAu3
metal· JVASP-126883· CrAu3
CrAu3 is an intermetallic compound composed of chromium and gold in a 1:3 atomic ratio, belonging to the gold-based intermetallic family. This material is primarily of research and specialized industrial interest rather than commodity use, valued for applications requiring the corrosion resistance of gold combined with chromium's hardening effects. CrAu3 finds application in high-reliability electronics, decorative coatings, and wear-resistant contact materials where gold's nobility and chromium's strength offer advantages over pure gold or conventional alternatives.
