Pb60Sn40 SW26

An alternative to the most popular solder wire (Sn60Pb40) with flux, for professional applications in automotive electrotechnics (starters, alternators).

Alloy designation in accordance with ISO 9453:2014: Pb60Sn40 (114)
Product type: Cored solder wire
Flux: SW26

1. General characteristics

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