Sn63Pb37 SW26
An alternative to the most popular solder wire (Sn60Pb40) with flux, for professional use.
Alloy designation in accordance with ISO 9453:2014: Sn63Pb37E*
Other known alloy markings: S-Sn63Pb37E*
Product type: Cored solder wire (with flux)
Flux: SW216
1. General characteristics
The product is intended for professional use. The solder Sn63Pb37E* 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 basic leaded alloy for manual, automatic and robotic processes used in industrial applications in electronics and electrical engineering, where meeting the requirements of the RoHS2 Directive is not required.
* higher cleanliness class.
