Aluminum Alloy Passivation Surface Treatment Tapping weld Screw

Aluminum alloy Passivation treatment spot welding screws.

 

Description

 

Welding screw is also called energy storage screw, electric bolt welding stud, or planting welding nail, etc.

Welding screw is used in a small range, which is only used in the sheet metal industry and the factory producing the case.

 

In order to improve the chemical stability of aluminum, passivation treatment is often used. It is to oxidize the aluminum surface, and there is a dense aluminum oxide film. The use of passivation agent makes the surface of aluminum form a dense aluminum oxide film, which has corrosion resistance and protects the aluminum in the inner layer from corrosion.


Passivation is to make the metal surface exhibit extremely low reactivity. Aluminum is a lively metal. From the perspective of its reducibility, it should be easy to interact with oxygen and water, but it does not work with both at room temperature. This is because a layer of oxide film is formed on the surface of aluminum to passivate the surface of aluminum.

 

Advantage:

1. There are no heavy metals, which are environmentally protection products.

2. Strong adhesion, easy to be adsorbed on the metal surface.

3. Will not cause excessive corrosion to the workpiece.

4. Easy to rinse, simple operation.
