Low silver (LOW-SAC) lead-free alloy in the form of solder bars, rods and wire for soldering applications in soldering aggregates.
Product name: Sn99Cu0,7Ag0,3 (SAC0307, TSC)
Alloy designation in accordance with ISO 9453:2014:
Product type: solder bars and rods, solder wire
1. General characteristics
The solder was produced in the first smelt of tin, silver 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 wire and bar meet the requirements of the RoHS2 Directive.
