Sn99,3Cu0,7 EVO11

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: EVO11

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. EVO11 solid flux is based on rosin and halide formulations. The solder alloy is intended for manual and automatic soft soldering where meeting the requirements of the RoHS2 Directive is required.
