## Features

- 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.
- Valued Pack: Each tube contains 21 sticks of 14" long brazing rods, total 0.5 (1/2) pound in weight. GREAT SAVING!
- 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.
- Versatile: A popular and economic solution for HVAC, Plumbing and Mechanical repairing. Ideal for gas welding, MIG and TIG welding, contact welding, HF brazing and some furnace welding. Perfect for brazing Copper to Copper, or Brass and Bronze joints in A/C, freezer, evaporator, heat exchange, water heater and etc. Cannot be used to weld iron or steel parts.

## Customer Reviews

### ⭐⭐⭐⭐⭐ With map gas it melts and flows
*by S***K on December 24, 2025*

Works great on copper up to #4 solid no flux needed

### ⭐⭐⭐⭐⭐ Good brazing rods
*by C***B on September 7, 2025*

Works as expected.

### ⭐⭐⭐⭐ Limited success with air acetylene or propane
*by B***B on August 31, 2023*

Worked on copper and galvanized steel air propane with good benzomatic torch, better flow with Hobart brazing flux granuals and with air acetylene torch. Fine for smaller copper on copper joining. Almost no flow on copper to stainless steel even with flux with these torches. Not as nice flow as brazing with some silver in the filler rod. Likely able to work with 1 in and larger with oxygen and flux.
