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 (AWS A5.8M/A5.8 BAu-6)

Class 2 Supplementary composition control Where no class is specified, Class 1 shall apply.
