Effect of small addition of Al to SnZn solder alloys

Abstract

The effects of Al on melting, microstructure and hardness properties of Sn9Zn lead free solders were investigated. SnZnAl solder in this study were produced via melting and casting method. Thermal properties (Tm) of the solder alloys were determined by Differential Scanning Calorimetry (DSC), mechanical properties were investigated by using Vickers Hardness and microstructure were observed by Scanning Electron Microscopy (SEM) and also element analysis were carried out by Energy Dispersive X ray (EDX).
