Pb50Sn50 SW26

An alternative to the most popular solder wire (Sn60Pb40) with flux. The product is intended for professional use.

Alloy designation in accordance with ISO 9453:2014: Pb50Sn50 (111)
Product type: Cored solder wire
Flux: SW26

1. General characteristics

The solder was produced in the first smelt of tin and lead. The composition of the solder complies with the ISO 9453:2014 standard. SW26 solid flux is based on rosin and halide formulations. It is leaded alloy for manual and automatic processes where meeting the requirements of the RoHS2 Directive is not required.
