Properties of Aluminum
Aluminum is a lightweight, corrosion-resistant metal that is used in a wide variety of industries, especially in the aerospace, automotive, electronics and construction industries. Key properties of aluminum include:
- Lightweight:
Aluminum’s low density makes it suitable for scenarios that require lightweight design. - Corrosion resistance:
The naturally occurring oxide film on the surface of aluminum resists corrosion, making it suitable for use in harsh environments. - Good thermal and electrical conductivity:
Aluminum has excellent performance in heat conduction and current transmission. - Easy processing:
Aluminum is easy to cut, weld and form, making it suitable for complex machining needs. - Recyclability:
Aluminum has a very high recycling value, making it an environmentally friendly choice.

Common Aluminum Parts Machining Methods
Surface Treatment of Aluminum Parts
Through surface treatment, the corrosion resistance, hardness, appearance and performance of aluminum parts can be enhanced to make them more adaptable to harsh working environments.
The following are common surface treatment processes for aluminum parts:
Cleaning is an important step in removing machining residues (e.g., oil, cutting fluids) from the surface of aluminum parts to provide a clean surface for subsequent coating treatments.
- Benefits: Removes contaminants and improves coating adhesion.
- Applications: All aluminum parts.
Anodizing forms a strong oxide film on the surface of aluminum through electrochemical reaction, which enhances its corrosion resistance, hardness and aesthetics. The process also allows for color dyeing, adding a different appearance to the product.
- Benefits: Improves corrosion and wear resistance; available in a wide range of colors; maintains the lightweight nature of aluminum.
- Applications: aerospace, automotive, electronic equipment housings, etc.
Electroplating is the electrolytic deposition of a layer of metal (e.g., nickel, copper) onto the surface of aluminum to provide additional protection and improve wear resistance and aesthetics.
- Advantages: Enhanced wear resistance and glossy appearance; improved electrical conductivity.
- Applications: electronic equipment, decorative parts, etc.
Painting is the formation of a protective layer on the surface of aluminum by spraying coatings to provide color, luster, and corrosion resistance. Commonly used coating materials include polyester and fluorocarbon.
- Advantages: Enhances appearance, corrosion resistance, and UV resistance.
- Applications: construction, home appliances, furniture, etc.
Phosphating treatment forms a phosphate film on the aluminum surface through a chemical reaction, improving corrosion resistance and providing better adhesion to the coating.
- Advantages: Enhances corrosion resistance and improves coating adhesion.
- Applications: automobile parts, mechanical equipment, etc.
Chemical Plating is a currentless plating method that deposits metals (e.g., nickel, copper) on the surface of aluminum parts through a chemical reaction, and is suitable for parts with complex shapes.
- Advantages: Uniform metal plating, improved corrosion resistance, suitable for complex shapes.
- Applications: electronics, aerospace, automotive, etc.
Deburring is the removal of burrs generated during the machining of aluminum parts to ensure a smooth surface of the parts and prevent the impact on assembly and usability.
- Advantages: Improve surface smoothness and assembly accuracy.
- Applications: precision machinery, electronic equipment, etc.
