Anodising is a surface treatment for aluminium used to provide a decorative surface, resistance to wear, resistance to corrosion and electrical insulation.
By electrolytic oxidisation of the surface in acid, a protective layer of oxide is formed, some 5-25 µ thick. The most frequent form of anodising is an uncoloured, naturally anodised surface. The layer of oxide can also be inked in different colours such as black, red, blue, purple, gold, champagne and green.
Small components as well as lengths of up to 6 metres can be anodised. In certain cases, we can also supply anodised materials of up to 12 metres in length.
Polished anodising and hard anodising are other available alternatives. Polished anodising means the surfaces are polished before anodising which results in a brighter surface. Hard anodising is carried out to obtain a very hardwearing surface layer.
All aluminium alloys can be anodised to give them an increased resistance to corrosion. Some alloys are more suitable for decorative anodising than others. Please refer to the technical information for more detailed information.
We are able to to carry out most forms of anodising. Do not hesitate to contact us for further information.
