Superior Powder Brazing Fluxes are all RoHS compliant.
Superior No. 601-Powder is a silver brazing powder flux active and protective to 850ºC/1,600ºF recommended for use with Copper, Copper-based alloys, ferrous metals, Gold, Silver, and other base metals. See our Silver Brazing White Flux Paste for paste form brazing flux.
Anti-Borax No. 2 is a brazing powder flux used for brazing brass, bronze, copper, steel, stainless steel, malleable iron and heat-resistant alloys. This flux promotes deep penetration of the filler metal in the joints, resulting in high bond-strength in manufacturing appliances, farm machinery, heat exchangers, maintenance, ship repair, steel furniture and welding equipment. For information about additional Anti-Borax products, go to Cast Iron Welding Flux, Forge Welding Flux or Welding Flux.
Superior No. 609B/3417-FP is a Boron-modified powder flux that is active and protective up to 1205°C/2200°F. It is formulated for brazing ferrous metals and alloys, high-chromium alloys and Tungsten Carbide compositions and is used for carbide tools, large steel parts, or when heating cycles are required.
