  • Без свинца
  • Dipping soldering
  • Tinning

Alloy designation in accordance with ISO 9453:2014:
Sn97Cu3 (402)
Product type: Solder bars and rods, Solder Wire

1. General characteristics

The solder was produced in the first smelt of tin and copper. The use of a continuous casting process ensures minimization of the generation of oxides in the solder. As a result, the phenomenon of the formation of dross in the soldering process is significantly reduced. The composition of the solder complies with the ISO 9453:2014 standard. The solder alloy intended for manual and automatic processes used in industrial applications. The solder bar, rod and solder wire meet the requirements of the RoHS2 Directive.
