Used in many contexts, the soft-soldering alloys in the Stella Welding Alloys catalogue present tin alloys in different compositions, with silver, copper, lead, antimony and zinc.
Soft alloys, or soft solders, are tin alloys for soft brazing, i.e. those operations in which the filler material has a melting temperature lower than 450 °C. Tin brazing is used in many fields, especially in electronics. Although initially the lead-tin alloy was the most used one (the best known is SnPb60/40), following the RoHS regulation (Restriction of Hazardous Substances Directive-RoHS, regulation 2002/95/EC), the majority of the production started to converge on copper-tin alloys or silver-tin alloys. They are mainly used for stainless steel and aluminium, electronics, electrical engineering and electromechanics.
