Product description


Anodizing is an electro-chemical process to transform the surface of aluminium to aluminium oxide. The resulting oxide layer is permanently connected with the aluminium. The layer thickness can be selected in the µ-range.


Hard-anodized layers are generated by anodic oxidation processes in cold electrolytes. By means of an electric current, a hard, ceramic layer of aluminium oxide is formed on the surface of the part. This layer consists mainly of amorphic y-aluminium oxide and forms of habitual, hexagonal cells perpendicular to the surface of the part.
