· JVASP-101017· Sn3Au

Sn3Au is an intermetallic compound in the tin-gold system, formed by the reaction of tin and gold at specific stoichiometric ratios. This material is primarily of research and specialized industrial interest, particularly in microelectronics and precious-metal joining applications where the thermal and mechanical properties of tin-gold phases offer advantages over conventional solder alloys or bulk gold in cost-sensitive precision 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.
