Alloy designation in accordance with ISO 9453:2014: 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 9453:2014 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 lead-free solder wire for manual and automatic processes used in industrial applications in electronics and electrical engineering, where meeting the requirements of the RoHS2 Directive is required.
