Aluminum surface treatment with color, masking and dimensional requirements specified together.
Anodizing converts the surface of suitable aluminum parts into an oxide layer. The alloy, surface preparation and specified treatment affect the final appearance and performance. Review the finish against the part's functional and cosmetic requirements.
Identify color, visible faces and the acceptance method for appearance. Mark surfaces that need masking, including electrical contacts or other untreated areas. Confirm how the treatment relates to critical dimensions and fits.
Specify the required anodizing process on the drawing where it is fixed. If it remains open, describe the environment, wear and appearance requirements. Confirm the agreed alloy and finish together before production.

Pros
Exceptional Wear & Abrasion Resistance: Creates a hard ceramic-like oxide layer (Type III Hardcoat can reach up to 60-70 Rockwell C). Superior Corrosion Resistance: Fully seals the aluminum substrate against moisture, salt spray, and harsh chemicals. Versatile Aesthetic Options: The porous unsealed oxide layer can absorb organic dyes, offering vibrant colors (Black, Red, Blue, Gold, Clear, etc.). Durable Electrical Insulation: Acts as a natural dielectric insulator.
Cons
Loss of Electrical Conductivity: Anodized aluminum becomes electrically non-conductive (insulative). Dimensional Growth: Adds measurable thickness (5–50+ µm depending on type), requiring pre-machining tolerance adjustments. Higher Cost & Complexity: Requires dedicated electrical equipment, higher power consumption, and longer processing times. Brittle Coating: Can craze or crack under heavy thermal expansion or fatigue flexing.
