Anodising is an electro-chemical process, which physically alters the surface of the metal to produce a tough oxide layer on the surface.
Anodising can provide an attractive, durable and tough finish to aluminium, enabling it to be used in many applications.
Anodising can have a varied processing time, which varies the thickness:
Anodising as an electrochemical process produces a protective aluminium oxide film, not all alloys are recommended for anodising.
The anodising process physically alters the surface of the metal, and also provides a means of colouring the metal.
During the process the oxide layer is at first porous, and it is at this point that its possible to add a coloured dye.
Anodising will give a high quality finish plus producing a finished product that will have excellent corrosive resistance and will not chip or peel off. Aluminium that has been anodised generally has a very long life span.
Normal anodising colours and finishes include gold, silver, black, natural, and satin. Other colours can be supplied.
Extrusions, or components can also be polished before anodising to give a bright reflective coating that has a long life.
