Soft Solders


Silver-tin alloys offer a number of advantages over tin-lead solders. They have excellent soldering characteristics of alloy flow, aesthetic appearance and wetting. They demonstrate improved strength characteristics over conventional tin-lead alloys, particularly where service at moderately elevated temperatures is a factor. Being lead-free they may be used in plumbing installations and food-handling equipment.

Comsol™ has excellent creep resistance when compared to tin-lead solders at room and elevated temperature.

Johnson Matthey's P40™ is a 4% silver-tin soft soldering alloy. P40™ has excellent soldering characteristics and offers a number of advantages over conventional tin-lead alloys. It provides improved strength characteristics particularly where service at moderately elevated temperatures is a factor.
Being lead free, P40™ may be used in plumbing installations, particularly where soft water is in use. P40™ is widely used in food handling equipment where lead contamination must be avoided.
P40™ is a good colour match on stainless steel and the resulting joints are not prone to interfacial (crevice) corrosion. The optimum joint gap for P40™ is 0.075mm.
