CoAu3
metal· JVASP-126882· CoAu3
CoAu3 is an intermetallic compound composed of cobalt and gold in a 1:3 atomic ratio, belonging to the family of precious-metal intermetallics. While primarily of research and specialized industrial interest rather than commodity use, CoAu3 exhibits high density and potential for applications requiring stable gold-cobalt phases, such as specialized coatings, wear-resistant surfaces, or high-temperature contacts where the combination of gold's corrosion resistance and cobalt's strength offers advantages over single-element alternatives.
