ANODISING
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.
ADVANTAGES OF ANODISING
There are several advantages to anodising:
- It increases the thickness and strength of the surface. The protective layer is a hundred times thicker than the natural layer and is thus more wear-resistant.
- The surface becomes corrosion-resistant, dirt-repelling and electrically insulating.
- The anodising layer is transparent, making it possible to add structure or colour to the surface.
- It gives the surface a nice shine with depth in the colour.
WHAT IS THE APPROPRIATE THICKNESS OF THE 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 |
