<p>NICKEL-PALLADIUM-CHROMIUM-BORON BRAZING ALLOY An improved brazing alloy, particularly suited for use in high temperature gas turbine engines, has a composition range which exhibits X-ray inspection capability, improved stress rupture properties, good ductility and oxidation resistance up to 1400.degree.F. The brazing alloy consists essentially of, by weight, about 20-80% Pd, 2-13% Cr, 1-4% B, balance being Ni and incidental impurities. The brazing alloy is capable of brazing in the 1800-2000.degree.F temperature range and is less costly than Au-bearing brazing alloys currently in use for brazing in this temperature range.</p> |
