· JVASP-75716· Cu2AsAu

Cu₂AsAu is an intermetallic compound combining copper, arsenic, and gold in a defined stoichiometric ratio, belonging to the class of ternary metal systems. This material is primarily of research and specialized metallurgical interest rather than widespread industrial production, with potential applications in electronics, thermoelectric devices, and high-reliability contacts where the combination of noble metal (Au) stability and copper's conductivity offers advantages in extreme or precision environments.

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.
