Anodized Finish Services

Professional anodized finish services for aluminum parts. Improve corrosion resistance, durability, and appearance with precision anodizing solutions for CNC machined parts.

Anodized finish is an electrochemical surface treatment process that enhances the natural anodized layer on aluminum parts. This process creates a durable, corrosion-resistant, and aesthetically appealing surface that is tightly bonded to the base material.

Unlike painting or coating, anodizing does not peel or chip. Instead, it becomes part of the metal itself, offering long-lasting protection and improved performance.

Anodizing is widely used in industries such as aerospace, automotive, electronics, and consumer products where both functionality and appearance matter.

iconAnodizing
DescriptionElectrochemical process that forms a durable, corrosion-resistant oxide layer on the surface of metals.
ServicesCNC Machining/Sheet Metal Fabrication/Stamping
Applicable MaterialsAluminum Alloy, Steel in Sheet Metals, Aluminum in Sheet Metals, Aluminum in Stamping, Copper in Sheet Metals, Copper/Brass in Stamping, Brass in Sheet Metals, SECC/SGCC in Stamping

pros

  1. Protects aluminum parts from oxidation, moisture, and harsh environments.
  2. Improves wear resistance and extends part lifespan.
  3. The anodized layer is integrated into the metal, ensuring long-term durability.

cons

  1. Anodizing is more durable and does not peel.
  2. Powder coating offers thicker coverage, while anodizing provides better surface integration.

notes

  1. To achieve the best results, consider the following design guidelines:
  2. Avoid sharp edges (may result in uneven coating)
  3. Maintain uniform surface texture before anodizing
  4. Account for dimensional changes (especially Type III)
  5. Use consistent aluminum grades for color uniformity
  6. Consider masking for selective anodizing
