Sn3Au
metal· 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.
