Anodising

What anodising is for aluminium parts, why it appears on CNC quotes, and what brands should specify for colour and finish.

What it is

Anodising is an electrochemical surface treatment commonly used on aluminium to improve corrosion resistance and create a durable finish, including coloured options.

Spec tip

Specify alloy suitability, colour references, and which faces are cosmetic. Anodising is a secondary process — confirm whether it is included in machining quotes.
