Sn99,3Cu0,7
Lead-free solder alloy in the form of solder wires, solder bars and rods for use in soldering aggregates.
Alloy designation in accordance with ISO 9453:2014:
Sn99,3Cu0,7 (401)
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 mechanized soldering in electronics, electrical engineering and other industrial applications where meeting the requirements of the RoHS2 Directive is required.
