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.
P40™
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.
Plumbsol™
Melting Range
221 - 225°C
Johnson Matthey Plumbsol™ is a 2.5% silver-tin soft soldering filler metal. Like P40™ this alloy is lead free. Plumbsol™ 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.
Plumbsol™ is a good colour match on stainless steel and the resulting joints are not prone to interfacial (crevice) corrosion.
The optimum joint gap for Plumbsol™ is 0.075mm.
P5™

Johnson Matthey P5™ is a 5% silver-tin soft soldering filler metal. Like P40™ this alloy is lead free. P5™ 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.
P5™ is a good colour match on stainless steel and the resulting joints are not prone to interfacial (crevice) corrosion.
The optimum joint gap for P5™ is 0.075mm.
97C
Melting Range
230 - 250°C
Johnson Matthey's 97C™ has a longer melting range than 99C™ and consequently builds up greater fillets and is a better gap filler. It is now being used extensively on automotive radiators.
99C
Melting Range
230 - 240°C
Johnson Matthey's 99C™ is a lead free solder which has a short melting range and good flow characteristics. It has been adopted as the universal plumbers solder.

Comsol™
Johnson Matthey Comsol™ is a high melting point (296°C) silver-tin-lead soft solder. It can be supplied as a solid wire, as a flux cored wire with rosin, synthetic resin or acid type fluxes and as a specially formulated solder paste.
A25™
Johnson Matthey A25™ is a 2.5% silver-lead soldering filler metal. It offers increased strength and creep resistance at elevated temperatures over conventional tin-lead solders. The silver addition improves wetting of A25™ onto copper and copper-based alloys and to a lesser extent on steels. Flow of the alloy is not as good as tin lead alloys. The optimum joint gap for A25™ is 0.2mm.
A5™
Melting Range
304 - 370°C
Johnson Matthey A5™ is a 5% silver-lead soldering filler metal. It offers increased strength and creep resistance at elevated temperatures over conventional tin-lead solders. The silver addition improves wetting of A5™ onto copper and copper-based alloys and to a lesser extent on steels.
Flow of the alloy is not as good as tin lead alloys and the alloy has a long melting range. The optimum joint gap for A5™ is 0.2mm.
