Abstract
A family of low temperature brazing alloys wherein the alloy is utilized in the form of a filler metal or shim and consists of electroplated nickel on zinc shimstock, wherein the zinc shimstock includes zinc, aluminum and silicon, with or without a small amount of lead, tantalum or bismuth. The use of the brazing alloys for joining aluminum parts together or an aluminum part to a part of another metal, such as brass. Further, metallic coating could be thermally spray coated and powder metals could be utilized as the filler materials with equally acceptable brazing techniques. Using these techniques, the brazing could be accomplished at a temperature in the range of 750 to 1050° F.
