The solidus temperature of sticks brazing rods is 1193°F / 645°C and the liquidus temperature is 1472°F / 800°C, the recommended joint space is 0.002" / 0.006" The 15% silver sticks brazing rods enhance the brazing alloy with improved wettability, higher strength and lower melting temperature, allowing the welding fluid to deeply into small brazing gaps so that the welded joint has higher strength and toughness, reducing brazing time, the brazing area and are clean before use With 64 pieces included in the pack, the silver brazing rods offer more reasonable allocation on various equipment using brazing rods in projects that require consistent filler performance and brazing rods with reliable efficiency The BCuP-5 silver brazing rods including 15% silver contain Silver () 14.5-15.5%, Phosphor ( 4.8-5.2%, and Copper (Cu) as remainder in the brazing rods with enhanced composition used for copper solder applications by brazing rods These brazing rods for copper hvac are suitable for areas that need strength, including air conditioners, refrigerators, compressors, and electrical motors using brazing rods for long-lasting performance, Weight: 1.14750607371 pounds, Manufacturer: Frewurwer
