SRA Anti-Borax #2 Bronze Brazing Flux – Powder Flux for Bronze, Brass, Copper, Steel & Stainless | Deep Penetration, Fast Oxide Removal, RoHS Compliant – Industrial Strength

Engineered for professional brazing applications, Anti-Borax No. 2 is a superior powder flux tailored for joining bronze, brass, copper, steel, stainless steel, malleable iron, and heat-resistant alloys. Compatible with a wide suite of filler metals—including silver (BAg), copper (BCu), nickel (BNi), brass (RBCuZn), and gold alloys—this flux offers versatile performance across demanding metal systems. Operating efficiently within a temperature band of 760–1205 °C (1400–2200 °F), this flux delivers deep penetration and high-strength bonds even in critical, high-temperature fabrications. Its active chemistry dissolves surface oxides rapidly with minimal bubbling, resulting in joints that are cleaner, stronger, and free from impurities and porosity. Anti-Borax No. 2 meets professional standards including MIL-F-16136B (Types A & B) and AWS A5.31-91 Type FB3J, and is RoHS compliant for quality and safety assurance in regulated environments. The flux may be used directly as a dry powder or mixed with water for a paste application—ideal for precise brushing onto joints or rods. Once brazed, residues wash off cleanly with hot water, simplifying post-brazing cleanup. Typical applications include appliance repair, farm machinery, heat exchanger fabrication, ship repair, steel furniture assembly, and maintenance in steel or alloy environments—all where professional brazing performance is critical.
