Gold-Nickel Alloy, Brazing Filler Metal, High Temperature, 82Au - 18Ni, 1740 °F (949 °C) Solidus-Liquidus Temperature AMS4787

This specification covers a gold-nickel alloy in the form of wire, rod, sheet, strip, foil, pig, powder, shot, and chips and a viscous mixture (paste) of 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 up to 1300 degrees F (704 degrees C), but usage is not limited to such applications. This filler metal is normally used for brazing, without flux, using a protective atmosphere.
