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.
