Package: Our pack contains 40PCS Brass brazing brazing alloy rods, each rod measures 2 mm 5/64 inches in diameter and 25 cm/ 9.85 inches in length. Recipe Optimization:Our Phos -copper brazing Rods conforms to A5.8. The chemical composition of the brazing rods: Phosphor (P): 6.6-7.4%, Copper (Cu): remainder. Low metling point 710-820. Solidus Temperature: 1310F / 710C, Liquidus Temperature: 1508F / 820C. Good fluidity during welding, molten metal can flow to small gaps Advantage: Phos Copper brazing alloy of air self-fluxing, with moderate melting point, high fluidity, perfect performance under methods of gas flame , induction, furnace brazing; Higher joint strength, better conductivity Perfect working for MAPP, MAP, propane and oxygen acetylene gas welding torch set-up. Also suitable for contact TIG welding. It is an ideal choice for both professionals and DIYers Wide Application: This BCuP-2 Suitable for resistance brazing, flame brazing, and high-frequency brazing. Copper-phosphorus brazing alloy is suitable for brazing copper and copper alloys, Widely used in refrigeration, home appliances, motors, electrical appliances, instruments and other manufacturing industries Self Fluxing Welding: The phosphorus in the brazing alloy acts as a brazing agent, so when brazing copper with copper-phosphorus brazing alloy, no brazing agent is required.
