ABSTRACT:
Brazing of metal parts employing a thin, homogeneous, ductile, filler metal foil is disclosed. The brazing foil, useful for brazing stainless steels, is less than about 0.064 mm (0.0025 inch) thick and has a composition consisting essentially of 0 to about 6 atom percent iron, 0 to about 21 atom percent chromium, 0 to about 4 atom percent molybdenum, 0 to about 5 atom percent tungsten, 0 to about 20 atom percent cobalt, 0 to about 19 atom percent boron, 0 to about 12 atom percent silicon, 0 to about 22 atom percent phosphorus, 0 to about 3 atom percent carbon and the balance nickel and incidental impurities. In addition to containing the foregoing elements within the above-noted composition ranges, the composition must be such that the total of iron, chromium, molybdenum, tungsten, cobalt and nickel ranges from about 70 to 84 atom percent and the total of boron, silicon, phosphorus and carbon ranges from about 16 to 30 atom percent. The ductile foil permits fabrication of preforms of complex shapes which do not require binders and/or fluxes necessary for brazing powders presently used to braze stainless steels and nickel base alloys.
