Effect of silicon addition on mechanical and electrical properties of Sn-Zn based alloys rapidly quenched from melt

► The quaternary Sn-12Zn-3Bi-0.5Si alloy has very good mechanical properties. ► The addition of silicon delays the fracture and improves the creep resistance. ► Electrical resistivity values are dependent on Si addition. ► The quaternary alloy has the most suitable properties required for solder applications.
