An alternative to the most popular solder wire (Sn60Pb40) with flux, for professional use.
Alloy designation in accordance with ISO 9453:2020: Sn63Pb37E (102)
Product type: Cored solder wire
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 standard. The solder contains rosin and halogen free flux. The flux PRO has good spread and its J-STD classification is ROL0. 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 RoHS Directive is not required.
* Higher cleanliness class.
