| Phosphor-Copper- Silver Brazing Alloy | BCu92PAg | rem. | 5.9-6.7 | 1.5-2.5 | 645-780 | 740-810 | High-silver class (above 10%) results in a narrower melting range and lower liquidus temperature, simultaneously improving wettability, capillary filling ability, joint toughness, and vibration resistance.Low silver content (below 10%) leads to lower costs.High silver increases toughness, while low silver decreases it.It possesses excellent electrical conductivity. Compared to phosphor-copper brazing filler metal (silver-free), the addition of silver reduces brittleness,improves corrosion resistance, and joint reliability. | Silver-containing phosphor copper brazing alloy can be used for brazing base materials of copper and copper alloys, but it is not suitable for brazing carbon steel, stainless steel, and nickel alloys.Applications include refrigeration and HVAC, gas appliances, plumbing and sanitary ware, electrical power, general machinery, and instrument hardware.Can be customized in rods, wires, rings, and sheets. | ||
