We offer a wide range of copper phosphorus brazing alloys primarily used for copper and copper alloy base metals (Brasses and Bronzes). Copper phosphorus brazing filler metals are primarily used in refrigeration, air conditioning and plumbing industry. The phosphorus content deoxidizes copper, and these filler metals can be used without a flux. The corrosion resistance of Copper Phosphorus joints is equivalent to that of copper. We can customize these products as per customers’ applications and specifications. These brazing alloys are available in rods, wires, strips, flat brazing rods, brazing rings, granules and preforms.
ALFA - 101A is particularly suitable for resistance brazing applications. This filler metal is more ductile and less fluid at brazing temperature than other filler metals containing more phosphorus. ALFA – 101, is the most commonly used Copper Phosphorus Brazing rods for joining Copper to Copper joints. It is extremely fluid at the brazing temperature. It will penetrate joints with very little clearance. ALFA - 101B is similar to ALFA102, but contains less silver. ALFA - 102 has high fluidity due to higher presence of phosphorus. It has ability to fill gaps at the lower end of its brazing range and is very fluid at high end. ALFA - 105 may be used where very close fits cannot be held. It is best used with the lower joint clearance. These alloys are majorly used in rods form in Air conditioning and Refrigeration industry. ALFA - 105A is more fluid than ALFA105 and has a lower liquidus temperature. It is extensively used in heat exchanger and tubing joints. ALFA - 106 is extremely fluid at brazing temperature. It provides more strength to joint than ALFA105. ALFA - 115 is extremely fluid at brazing temperature. The phosphorus inclusion gives the filler metal a self-fluxing property on copper. It provides high strength to the joint.
