Feature●Self Fluxing: USA USA AWS A58 Class: BCuP-2 brazing alloys rods. Contents: Phosphor (P): 6.6-7.4%; Copper (Cu): Rest. This brazing alloy is close to eutectic crystal composition. It is self fluxing and do not need any brazing flux when soldering copper to copper or copper to brass joints, while for brazing brass to brass parts, Bluefire JFB-102 brazing flux is recommended for best results.●Best Performances: Solidus Temperature: 1310°F / 710°C, Liquidus Temperature: 1508°F / 820°C. Recommended joint clearance: 0.002"/0.007", Fluid Rating: 5. JCuPB brazing rods contain lesser phosphors, resulting a much better plastic performances and a little higher melting points.●All Purpose: The torch head is suitable for soldering,removing tile,lighting grills, plumbing repair, glass work and softening caulk/putty. Adjust the handy bracket to convenient position for holding or hanging,save your space well.●Multiple Fuel Options: Threading is compatible with CGA600 US standard fuel gas cylinders, a variety of fuels can be used including MAPP, MAP Pro (Propylene) and Propane. For better performance, it’s recommended to use with Bluefire Modern MAPP/PROPANE GAS.●Powerful Torch: Handy torch head only, gas cylinder shown in the photo is for illustration only. Powerful Flame provides maximum temperature up to 2350°F(1288°C), high output up to 7481BTU/hr,consumption rate is 161.2g/hr(2.19kw).Description FAVORCOOL JCuPB phosphor- -copper brazing alloy is a material with the binary alloy of copper- phosphors base,which has good mobility ,low cost ones and processing property.It applies to contact welding,gas flame welding,HF brazing and some furnace welding.Phosphor-copper brazing alloy has self- brazability and doesn t need brazing flux. But flux is required whilebrazing brass to brass.American Standard:BCuP-2 HB-911A torch head made by brass material, sturdy and durable, which can withstand higher temperature.
