Gold Filler Metals for Brazing, Welding Wire — BAu-3

BAu-3

BAu-3 is used to join steels, stainless steels, nickel based alloys and other materials, where ductility and resistance to oxidation or corrosion is necessary. Gold filler metals readily wet most base metals, including the super alloys, and are especially good for brazing thin sections due to their low interaction with the base metal. Good for Nickel, Molybdenum, Stainless Steel, Kovar, and Mo/Mn– Low Penetration. We recommend a maximum brazing temperature of 1950°F.

Those containing nickel may be used at higher temperatures.
