Sn167Au833
metal· Sn167Au833
Sn167Au833 is a tin-gold intermetallic compound or alloy system with approximately 83.3% gold and 16.7% tin by atomic ratio, representing a high-gold binary phase. This material belongs to the Au-Sn family of intermetallics, historically significant in electronics manufacturing and jewelry applications where controlled melting behavior and metallurgical bonding characteristics are valued. The gold-rich composition makes it suitable for high-reliability interconnect systems and specialty joining applications where thermal stability and corrosion resistance are critical.
