Abstract
A nickel based high melting point, homogeneous, ductile brazing foil composition consists essentially of about 17 to 20 atom percent chromium, about 4 to 10 atom percent boron, about 10 to 16 atom percent silicon, the balance being nickel and incidental impurities. The composition is such that the total of nickel and chromium ranges from about 74 to 84 atom percent.
Claims5
A homogeneous ductile brazing foil having a composition consisting essentially of 17.5 to 18.5 atom percent chromium, 12.5 to 13.5 atom percent silicon and 5 to 6 atom percent boron, the balance being nickel and incidental impurities.
