Anodizing

The Sapa research and technology are employed also in downstream metal workings. By means of the anodizing treatment, which is the finishing of the natural surface of aluminium, an oxide protective layer is formed even in the least accessible areas. The making of a correct pre-treating before the oxidization process is an essential condition for end product quality.
