5-8um Anodized Aluminum Parts For Industrial Mechanical Components Anodizing Die Cast Aluminum

Our anodized aluminum parts undergo specialized surface treatment using electrolyte solutions to enhance aluminum and its alloys through the anodizing process.

Anodizing is an electrochemical process that grows a stable oxide film on metal surfaces. For aluminum products, this creates a protective, decorative, and functional oxide layer when subjected to current in specific electrolyte conditions.

• Creates oxide films with hardness exceeding the base aluminum
• Significantly improves wear resistance and durability
• Standard classification includes Type I, II, and III anodizing
• Standard film thickness: 5-8μm (Type II Anodizing)

• High-voltage electrochemical reaction process
• Extended processing time (typically tens of minutes)
• Produces thick films (tens to hundreds of microns)
• Excellent mechanical properties and corrosion resistance
• Superior wear resistance and weatherproofing
• Strong adsorption capabilities

Anodized aluminum parts are widely used in:

• Mechanical components and precision instruments
• Aircraft and automotive parts
• Radio equipment and consumer goods
• Architectural decoration elements
• Wear-resistant components (engine cylinders, etc.)

Note: Standard anodizing (Type II) is not recommended for cast aluminum due to poor surface finish and limited color options (typically only black).
