CuSnAu
metal· JVASP-149337· CuSnAu
CuSnAu is a ternary copper-tin-gold alloy that combines the corrosion resistance and workability of copper with tin's strengthening effects and gold's nobility. This material class is primarily used in high-reliability electrical contacts, connectors, and decorative applications where corrosion resistance, wear resistance, and aesthetic properties are critical; the gold component ensures oxidation resistance while maintaining cost-effectiveness compared to pure gold systems.

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.
