Our anodising processes are typically applied to machined aluminium parts to reduce corrosion and add an appealing metallic colouring to the porous aluminium substrate. Anodising helps parts resist scratching, is a natural electrical insulator, and is one of the most durable finishes available. We offer three specific types of quick-turn anodising options to protect your parts:  

Decorative Anodising ISO 7599

equivalent to -Type II

  • Class 1 (clear)   
  • Class 2 (black)    

Hard Anodising ISO 10074

equivalent to - Type III (hard coat)

  • Class 1 (black)

Chromate Plating

Chromate conversion coating protects your parts from corrosion by chemically changing the properties of the metal. It also offers electrical connectivity and the ability to paint the part. Our chromate plating is Chromate Conversion Non-Hexavalent | SurTec(R) 650.
