Anodising aluminium for aesthetic and protective purposes

Before extolling the virtues of anodised aluminium let’s clarify the anodising process itself.

Anodising is an electrolytic process which has been established in the architectural sector for the past seventy years.

Aluminium naturally possesses an oxide film on its surface. This oxide film acts as a barrier to corrosion and is the one of the main reasons aluminium is considered a low maintenance and therefore cost effective metal.

During the anodising process, the natural oxide film present on the metal’s surface is thickened by an electrolytic treatment into a hard abrasion resistant finish.

The thickened aluminium surface has a number of advantageous properties as compared with aluminium in its raw state. These significant advantages include the development of a silky smooth satin finish and a surface which is also more resistant to knocks and scratches and general wear and tear.

The integral nature of the anodised finish ensures surface patterns and detailing can be preserved and also enhanced by reducing surface reflection.

You can view some impressive test results that compare the abrasion resistance of aluminium flat bar in the untreated and anodised conditions. The test results, carried out by CERAM Research, show the anodised aluminium flat bar being 4 times more resistant to surface marking than its mill finish counterpart.
