Nickel palladium base brazing alloy

摘要

A brazing alloy composition consisting essentially of from about 17 to about 44 percent by weight of palladium, from about 4 to 11 percent by weight of chromium, from about 1 to about 4 percent by weight of silicon from about 1.5 to about 4 percent by weight of boron and the balance nickel is suitable for brazing in the temperature range of from about 1750 DEG F. to about 1850 DEG F. with a recommended brazing temperature of about 1800 DEG F. The brazing temperature of the brazing alloy of this invention is lower than the brazing temperatures of conventional Ni-base phosphorus-free brazing alloys and has good stress-rupture characteristics and oxidation resistance up to 1400 DEG F.
