Description / Abstract:

Form

This specification covers a gold-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.

Application

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 °F (704 °C), but usage is not limited to such application. This filler metal is normally used for brazing, without flux, using a protective atmosphere.

Classifications

Filler metal supplied to this specification is classified (see 8.4) as follows:

Class 1 - Standard composition (AWS A5.8 BAu-4)

Class 2 - Supplementary composition control
