## Description

Bluefire 21 Sticks JCuPB 1/2 lb Self Fluxing Phosphor Copper Brazing Alloy Welding Rods No Need for Flux 0.050" x 1/8" x 14" Industry BCuP-2 Professional Grade Propane Gas Soldering Torch Supply

## Features

- A material with the binary alloy of copper phosphors base.The temperature of the liquid phase is 1508 F. The temperature at which it melts from a solid to a liquid is 1508 F.
- Self flux：that means the melting alloy fluid has a very good flowability, it will flow to every direction flat on the surface, and penetrate into deep shallow gap between the welding parts.
- Flux Free : you DON'T need any flux when using Phosphor Copper alloy to brazing
- Magic material： when the percent of P in the alloy is over 6%, you will see a dramatical drop in the melting point of the alloy (around 200 300 C drop from pure copper)
- Specificity：the brazing alloys which contains P cannot be use to weld any iron or steel parts.
