    Anodic oxidation

    Aluminum finishing by Coatinc

    Our anodic oxidation processes achieve even better results than other processes of surface finishing performed by our company group for steel and metal. Our technologies not only allow special protection, but also provide you with the highest flexibility of visual design. You can count on 100 % durability without having to make concessions regarding the visual effect. On the contrary: Feel free to achieve the results you want! We will support you in the process.

    How does anodic oxidation work?

    Aluminum parts are connected with a positive pole (anode) in a bath containing diluted sulphuric acid. The electrochemical process produces oxygen, which combines directly with the aluminum and produces aluminum oxide. Pigments and other substances can be applied to the newly-created aluminum oxide immediately after anodizing, resulting in the individual metallic colouring. The surface transforms into a sealed layer as a result of the sealing process, in which the pores of the layer are packed tight. This is not only resistant to corrosion, but also remains clean and retains its colour. Anodized aluminum is easy to recycle as the aluminum is protected by a metallic layer.

    Product dimensions

    In principle, we perform various anodic oxidation processes within the scope of our standard product dimensions. However, we also make the maximum (or minimum) possible for you: Please contact us, and we will prepare a specific process bath for individual dimensions.
