Anodic Oxidation

Also known as anodizing, it performs an electrochemical transformation of the aluminum surface, creating an extremely hard and compact oxide layer. These characteristics, combined with excellent corrosion resistance and high electrical insulation, have made this treatment successful in the field of light alloys.
Supergalvanica has a robotic anodic oxidation plant, ideal for producing large series with precision and uniformity.
Technical Characteristics
We mainly perform colorless anodic oxidation. The surface appearance can vary from matte to glossy depending on the base material and the degree of satin finishing performed according to customer requests. The thickness of the treatment can vary from 3 to 25 microns depending on customer requirements.
Frequently Asked Questions
5Anodic oxidation, or anodising, is an electrochemical process that transforms the aluminium surface creating an extremely hard and compact oxide layer. Unlike other galvanic treatments that add material, anodising converts the metal surface itself, ensuring perfect and permanent adhesion.
Yes, Supergalvanica has a robotic plant dedicated to anodic oxidation, specifically designed for large series production with constant precision and uniformity. Automation ensures repeatability and quality even at high volumes.
Yes, anodic oxidation involves oxide layer growth that is approximately 50% penetrating into the material and 50% growing on the surface. Thickness can range from 3 to 25 microns. For tight-tolerance applications, this factor should be considered in part design.
Anodic oxidation offers far superior wear and corrosion resistance compared to painting, as the protective layer is an integral part of the metal rather than an overlaid coating. It does not peel, flake, or detach, and offers excellent electrical insulation. Painting, however, can offer more colour options.
Yes, the oxide layer created by anodising is extremely hard and compact, offering excellent resistance to abrasion and wear. This makes the treatment ideal for mechanical components subject to friction and repeated contact.
