Abstract

Lead is an element which was being used traditionally in soldering because of its low melting point. However, lead is poisonous and increasing research is being carried out on developing lead-free soldering alloys. In this work, two lead-free alloys, namely 87Sn–7Zn–3Al–3In and 87.5Sn–6Zn–2Al–2.5In were melted by induction melting with pure argon atmosphere. Vicker’s hardness test was conducted and also the pasty range of the alloy was found using Differential Scanning Colorimetry (DSC). Hardness values were higher than normal lead-based soldering alloys and the pasty zone was comparable to normal lead-based alloys. The lead-free solders were characterized with Energy Dispersive X-Ray Spectra (EDS). Microstructural characterization was also done to corroborate results.
