Sn99,3Cu0,7 EVO

Lead-free solder alloy with flux, for universal use in electronics and electrotechnics.

Alloy designation in accordance with ISO 9453:2014:
Sn99,3Cu0,7 (401)
Product type: Cored solder wire
Flux: EVO

1. General characteristics

The solder was produced in the first smelt of tin and copper. The composition of the solder complies with the ISO 9453:2014 standard. EVO solid flux is a “no clean”, based on rosin and carefully selected activators. The solder alloy is intended for manual and automatic soft soldering where meeting the requirements of the RoHS2 Directive is required.
