Lead-free solder alloy in the form of solder wire and bar for a wide range of industrial applications.
Product name: Sn96,5Ag3Cu0,5 (SAC305)
Alloy designation in accordance with ISO 9453:2014: Sn96,5Ag3Cu0,5 (711)
Product type: solder bars, 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, rod and bar meet the requirements of the RoHS2 Directive.
