Basic lead-free solder wire with flux for a wide range of industrial applications.
Alloy designation in accordance with ISO 9453:2020: Sn96,5Ag3Cu0,5 (711)
Product type: Cored solder wire
Flux: PRO
1. General characteristics
The solder was produced in the first smelt of tin, silver and copper. 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 lead-free solder wire for manual and automatic processes used in industrial applications in electronics and electrical engineering, where meeting the requirements of the RoHS Directive is required.
