· JVASP-100147· Ag3Au

Ag₃Au is a gold-silver intermetallic compound representing a specific stoichiometric phase in the Au-Ag binary system. This material is primarily of research and materials science interest rather than a high-volume engineering material, valued for studying phase behavior, solid-state diffusion, and metallic bonding in precious metal systems. Industrial applications are limited but include specialized jewelry alloys, dental restorations, and advanced electronics where the combined properties of gold and silver—such as corrosion resistance, electrical conductivity, and biocompatibility—offer advantages over single-metal alternatives, though cost and availability typically restrict use to niche, high-value applications.

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.
