Almit SR-37 Lead Free Cored Solder Wire is a no clean solder wire which has been developed for manufacturers who require silver containing lead free materials.The addition of silver allows the lowest melting point to be attained and increases the wetting performance of the lead free alloy. Almit SR-37 LFM-48S Cored Solder Wire uses the proven SR-37 flux which has been especially developed for use with lead free alloys. It features fast wetting to all materials, including many so called difficult to solder types and the post soldering residues possess high surface insulation resistance.The LFM-48S alloy is based on a tin / silver / copper formulation but has additional elements added, which together with the SR-37 flux, slow down the erosion of soldering iron tips and thus produce more cost savings.
