TECHNICAL DATA SHEET
Alloy designation in accordance with ISO 9453:2014 Sn60Pb40
Other known alloy markings S-Sn60Pb40
Product type Cored solder wire (with flux)
Flux PRO
1. General characteristics
The product is intended for professional use. The solder was produced in the first smelt of tin and lead. The composition of the solder
complies with the ISO 9453:2014 standard. The solder contains rosin and halogen free flux. The flux PRO has good spread and its J-STD
classification is ROM0. 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.
