Brass Brazing Alloy Preforms
These are base metal alloys used for high temperature brazing of steels & tungsten carbide. Cost effective alternative to silver brazing alloys wherein high joint strength can be readily achieved. Some alloys also offer excellent corrosion resistance with high thermal and electrical conductivity. Saru Silver offers these alloys in a wide range of compositions to suit specific applications available in Wires and Rods, Strips, Wire Flattening, Wire Preforms, Strip Preforms, Granules and Spheres. With the help of the chart below, identify and compare alloys of our Brass and Bronze Brazing Alloys suited to your needs.
