Anodizing (Colorless and Colored)

Anodizing is a process applied to aluminum parts, which consists of creating a porous layer of oxide by immersing the part in an electrolytic bath (in the case of Anodfarbe, a sulfuric bath). This layer stabilizes the oxidation process, giving the aluminum extra protection against corrosion. Furthermore, it also serves as an electrical insulator and provides an improved aesthetic appearance when pigmented with colors.
It is possible to impregnate the porous oxide with colored pigments, giving the piece the color desired by the customer.
In the final phase, sealing is carried out, where the pores of the aluminum oxide layer are filled. This is the last step in the aluminum coating process, and is essential for obtaining a durable, corrosion-resistant oxide layer.
