· JVASP-126543· Rh3Au

Rh₃Au is an intermetallic compound combining rhodium and gold in a 3:1 atomic ratio, belonging to the family of precious metal alloys used in high-performance applications. This material is primarily of research and specialized industrial interest, valued in catalysis, jewelry metallurgy, and electronics where the combination of rhodium's catalytic activity and chemical resistance with gold's stability and conductivity provides synergistic benefits. Rh₃Au is notable for applications requiring exceptional corrosion resistance, thermal stability, and surface properties that cannot be achieved with single-element precious metals or conventional alloys.

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.
