· 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.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
