Bi4Au
metal· JVASP-101068· Bi4Au
Bi₄Au is an intermetallic compound in the bismuth-gold binary system, representing a specific stoichiometric phase that combines a brittle bismuth-rich matrix with gold. This material is primarily of research and specialized industrial interest rather than a commodity structural material; it appears in fundamental materials science studies of binary phase diagrams and intermetallic behavior, with potential applications in thermoelectric materials, specialized soldering systems, and gold-bismuth brazing alloys where the phase stability and melting characteristics are exploited.

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.
