Gold Brazing Filler Metals
Gold brazing alloys are used for the brazing of iron, nickel, and cobalt base metals. Gold alloys provide a greater resistance to oxidation, corrosion, and ductility, which can play an important role in the service of the part. Prince & Izant recommends brazing gold alloys by way of induction, furnace, or resistance heating in a protective atmosphere, which includes vacuum and does not require flux. A borax-boric acid flux is used when the application requires a flux.
