Foshan Nanhai Shuangfu Chemical's Aluminium Brazing Flux is mainly used in:

1. Clean the surface

One of the primary purposes of using Aluminium Brazing Flux is to clean the surface of the aluminum parts

that are to be brazed. The flux helps in removing any oxidation or surface contaminants

that can interfere with the brazing process.

2. Prevent Oxidation

The Aluminum Brazing Flux creates a layer over the aluminum surface and

protects it from oxidation. This also helps in reducing the formation of thick oxide layers that can be difficult to remove.

3. Improve Wetting Properties

The flux helps in improving the wetting properties of the aluminum by

making the surface more receptive to molten filler metal. This improves the flow and

adhesion of the filler metal to the aluminum surface.

4. Improve Joint Strength

By improving the wetting properties of the aluminum, the use of Aluminum Brazing Flux

also helps to improve the joint strength and the overall quality of the braze joint.
