ABSTRACT:
Brazing of metal parts employing a low temperature, high strength metal alloy is disclosed. The alloy has a composition consisting essentially of about 6.10 to 6.66 atom percent chromium, about 2.43 to 2.46 atom percent iron, about 10.06 to 25.10 atom percent boron, about 3.22 to 12.85 atom percent silicon and the balance essentially nickel and incidental impurities, the composition being such that the total of nickel, chromium and iron ranges from about 71.68 to 74.58 atom percent and the total of boron and silicon ranges from about 25.42 to 28.32 atom percent. Such an alloy is suitable for brazing .gamma.' superalloys and stainless steels at temperatures ranging from about 927.degree.-1010.degree. C. to provide strong, low cost joints.
