Anodising is a method for surface-treating aluminium materials. Aluminium does not corrode, but is subject to a process of natural oxidation. This natural protection process can be imitated through anodising, also called anodic oxidation.
There are several advantages to anodising:
The thickness of the anodising depends on the function and use context of the product. The table below is a guideline for the appropriate thickness of the anodising:
3 my | Protection in connection with processing |
5 my | Indoors with no functional use |
10 my | Indorrs with functional use |
15 my | Outdoors in mild corrosion environment |
20 my | Outdoors in normal corrosion environment |
25 my | Outdoors in severe corrosion environment |
min. 10 my | Items requiring a specific colour |
