Precision CNC anodizing treatment for aluminum parts

Process Introduction

By using anodizing technology, a dense oxide film is generated on the surface of CNC processed aluminum products to enhance hardness, corrosion resistance, and appearance texture.

Core Features

High hardness: The surface hardness can reach HV 300-500 (hard oxidation), and the wear resistance is significantly improved

Corrosion resistance: Salt spray test>300 hours, suitable for harsh environments

Diverse Appearance: Available in natural color, black, silver, and customized colors, with matte/glossy options available

Dimensional stability: uniform film thickness (5-50 μ m), does not affect precision fit dimensions

Applicable Products

3C electronic product casing

Automotive aluminum alloy components

Medical device structural components

Industrial equipment panels and handles

customization capability

The film thickness, color, and glossiness can be controlled according to the drawing requirements

Provide pre-treatment combination processes such as sandblasting, wire drawing, polishing, etc

quality assurance

Film thickness testing+color difference control+adhesion testing 

Compliant with RoHS standards and environmentally compliant

delivery cycle

Batch product oxidation treatment takes 3-5 working days (can be synchronized with CNC machining scheduling)
