Johnson Matthey Silver-flo™ 56 Cadmium Free Silver Brazing Paste
Categories: Metal; Nonferrous Metal; Precious Metal; Silver Alloy; Solder/Braze Alloy

Material Notes: Silver-flo™ 56 Brazing Paste is a custom made solution for improving the quality and production rate of brazing operations. It consists of Silver-flo™ 56 powder, a cadmium-free silver brazing filler metal, combined with a flux-binder system to form a smooth dispensable paste.

The use of a brazing paste provides the opportunity for automation or semi-automation of the brazing process by de-skilling and allowing pre-placement of the brazing material. It reduces handling, waste and can improve joint quality by helping to provide repeatability in brazing.

The filler metal, Silver-flo™ 56, combines a low brazing temperature with a short melting range is very free flowing and produces neat joints with small fillets. These characteristics make Silver-flo™ 56 an excellent general-purpose silver brazing filler metal.

Silver-flo™ 56 Brazing Paste is an extremely versatile product and has been used in a range of diverse applications from the brazing of electrical contacts, to pipes in musical instruments or the tubes and brackets in shot guns for example.

Silver-flo™ 56 can be used to join all the common engineering materials (excluding aluminum) such as copper, copper alloys (including, brasses, bronzes, gun metal, nickel silvers, aluminum bronze, copper nickel), steels including, mild, carbon, tool steel, stainless steels, low alloy steel), tungsten carbide and PCD segments. On large or difficult to wet tungsten carbide pieces specialized silver brazing filler metals containing nickel / manganese are often preferred.

Paste Grades: 106-B1-70, 180-B1-75
