· JVASP-104560· Bi3Au

Bi₃Au is an intermetallic compound formed from bismuth and gold, belonging to the family of precious metal alloys and intermetallic phases. This material is primarily of research and specialized industrial interest rather than a mainstream engineering commodity. Applications are limited to niche sectors including thermoelectric devices (where bismuth compounds are valued for their Seebeck coefficients), high-reliability electronics and interconnects, and potentially wear-resistant or specialized coating systems where the combination of bismuth's low melting point and gold's chemical stability offers processing or functional advantages.

Export Control

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.
