About Anodising

Anodising is a finishing process for aluminium components.  CNC machined components are often anodised for cosmetic appearance and corrosion resistance.

The anodising process involves creating a thick and durable oxide layer that is porous.  A coloured dye is introduced to these pores and then sealed to create a durable finish.  Clear anodising is done without dye if a colour is not required.

Advantages of anodising:
Thicker oxide layer provides better corrosion protection
Wide range of colours from clear to black
Addition of colour does not add to the thickness of the part. Critical sizes are not altered during the process
Hard anodising can be used to create hard wearing surfaces up to 60 Rc
Anodised surfaces do not transfer heat as readily as natural aluminium. Handrails and park benches are anodised so that they are not as hot to touch when they have been in the sun.

TNN can make your aluminium part and anodise them to your specifications.  We can also perform post anodising machining and engraving.
