Gold-Palladium-Nickel Alloy Brazing Filler Metal, High Temperature 50Au - 25Pd - 25N i2015 to 2050 °F (1102 to 1121 °C) Solidus-Liquidus Range
This specification covers a gold-palladium-nickel alloy in the form of wire, rod, sheet, strip, foil, pig, powder, shot, chips, preforms, and a viscous mixture (paste) of the powder in a suitable binder.
This filler metal has been used typically for joining corrosion and heat resistant steels and alloys where corrosion and oxidation resistant joints with good strength at elevated temperatures are required, but usage is not limited to such applications.
Filler metal supplied to this specification is classified as follows:
Class 1 Standard composition
Class 2 Supplementary composition control
Where no class is specified, Class 1 shall apply.
