US Classification:

228 563, 228246, 22826251, 428652, 428654

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.

Abstract:

A brazing product for low temperature fluxless brazing comprises a filler metal-forming composition which melts in the range from about 380-575 C. The filler metal-forming composition comprises zinc optionally in combination with aluminum and/or silicon, and further comprises at least one braze promoter selected from nickel, cobalt, iron and palladium. The filler metal-forming composition may comprise a single layer or may comprise a number of distinct layers. The brazing product may take the form of a brazing preform or a brazing sheet or casting in which the filler metal-forming composition is deposited on a non-consumable substrate. The substrate may preferably comprise aluminum or an aluminum alloy, but may instead be comprised of one or more metals other than aluminum.
