· JVASP-123783· Bi5Au

Bi₅Au is an intermetallic compound composed primarily of bismuth with gold, representing a specialized metal alloy in the bismuth-gold binary system. This material is primarily of research and materials science interest rather than established industrial production, with potential applications in low-melting-point solders, thermoelectric devices, and specialized electronic interconnects where bismuth-based compositions offer advantages in thermal or electrical properties.

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.
