Clear anodizing

We offer clear anodizing services that produces a translucent oxide layer that allows some of the underlying metal material to show through. It’s often used for engineering components, kitchen utensils and other parts where a natural look is desired.

Colour anodizing

We offer colour anodising services by colour dipping or electrolytic colouring. This type of anodizing is often used on external automotive parts, enclosures and other products where a decorative finish is desired.

Why Use Anodizing For Your CNC Parts?

Anodizing vs Alodine

Anodizing will result in a non-electrically conductive aluminium whereas alodine will help preserve conductivity of aluminium parts. Anodizing is also a more durable finish that can withstand more wear and tear than an Alodine finish.

Main advantages of anodizing

  • Extends part’s life span
  • Hardens part surface
  • Excellent corrosion and wear resistance
  • Provides better thermal insulation
  • Lends an attractive metallic look

Things to keep in mind before anodizing your part


  • Results in electrically non-conductive aluminium parts
  • May change dimensions and tolerances due to added coating
  • Expect that colour matching will never be 100% accurate
  • A portion of the part surface is likely to not become anodized

How does anodizing work?

Anodising is an electrochemical process that converts a metal surface into a decorative, anodic oxide finish. The process can be divided into five basic parts: preparing the surface, anodizing itself, cleaning the parts, adding colour and sealing the pores.

Anodizing FAQs

The main purpose of anodizing is to improve properties such as wear resistance, corrosion resistance, durability aesthetics, heat dissipation, dielectric (non-conductive) properties and adhesion of Aluminium and other metal parts.

The main disadvantages of anodizing include:

  • Limited colour selection
  • Inconsistency of colour shades between batches
  • Cannot be used on stainless steel
