AIM Sn63/37Pb Electropure™ is a high purity alloy that is composed of 63% tin and 37% lead. Electropure™ is alloyed in a proprietary method that results in a low drossing, high wetting solder. The Electropure™ process reduces suspended oxides in the solder, thus reducing drossing, improving flow, and reducing bridging during soldering. 63Sn/37Pb is a eutectic alloy with a melting point of 183°C (361°F). Typical applications are wave soldering and plating where 63Sn/37Pb is primarily used as a coating for corrosion protection, and as a base for soldering.
