6063 surface treatment of aluminum alloy auto parts
6063, surface treatment is very important as it improves the corrosion resistance and aesthetics of the part. Here are some common surface treatments:
Anodizing treatment: improves corrosion resistance by forming an oxide film on the aluminum surface. Oxidation treatment can use anodic oxidation or sulfuric acid oxidation and other methods, common colors are black, silver, gold, blue and so on.
Polishing treatment: polishing treatment can make the aluminum surface smoother and improve its aesthetics. Commonly used polishing methods include mechanical polishing, chemical polishing and electrolytic polishing.
Spray treatment: improve corrosion resistance and aesthetics by spraying specific paint or pigments on the aluminum surface. Common spray coatings include coating paint, polyimide, etc.
Coating treatment: improve corrosion resistance and aesthetics by coating a layer of metal or alloy on the aluminum surface. Common coatings include chrome plating, nickel plating, and electro-galvanizing.
When choosing a surface treatment, factors such as the specific use of the part, the characteristics of the material, and the cost need to be considered.
Specific application of 6063 aluminum alloy in automobiles
The application size of 6063 aluminum alloy in automotive parts varies with specific applications. The following are some typical application introductions:
Automobile body structure: in the automobile body structure, 6063 aluminum alloy is often used in the production of door frames, roof frames, window frames and other parts.
