Sn40 Pb60 :- For soldering of brass and car radiators. For bulk soldering, and where wider melting point range is desired. For joining cables. For wiping and joining lead pipes. For repairs of radiators and electrical systems.
Sn50 Pb50 :- “Ordinary solder”, for soldering of brass, electricity meters, gas meters, formerly also tin cans. General purpose, for standard tinning and sheet metal work. Becomes brittle below −150 °C. Low cost and good bonding properties. Rapidly dissolves gold and silver, not recommended for those. For wiping and assembling plumbing joints for non-potable water.
Sn60 Pb40 :- Common in electronics, most popular leaded alloy for dipping. Low cost and good bonding properties. Used in both SMT and through-hole electronics. Rapidly dissolves gold and silver, not recommended for those.
