High performance copper and copper alloy welding rod for brazing tungsten carbide

High Performance Copper and Copper Alloy Welding Rod for Brazing Tungsten Carbide

With 10 years of experience in the production of tungsten carbide combined with our specialised grade of materials, we can offer the most suitable solution

for each application.

1. Product Description:

Brazing is the process of joining two independent pieces of metal to form one strong

load-bearing joint. As a professional manufacturer of tungsten carbide products, our 

tungsten carbide components are commonly joined to steels and other materials by brazing.

Under the right conditions all common braze alloys from pure copper to silver alloys will

readily wet cemented carbide surfaces.  Copper is typically used as the brazing material

for high temperature application.

2. Product Specification:

The basic brazing steps follow:

1. Lightly apply flux to the steel surface.
2. Position a precut piece of braze alloy on the steel and lightly coat with flux.
3. Position the tungsten carbide component and coat the outside surfaces with flux.
4. Heat the assembly evenly throughout its volume to the proper temperature.
5. Once the braze alloy is molten, jiggle the carbide slightly to allow any flux or fumes to escape. Do not press too firmly or the braze alloy will be forced out of the joint.
6. Allow the assembly to cool slowly. Make no attempt to cool the assembly quickly.
7. Wash off any excess flux with hot water.
