Even more versatile aluminium

In short, anodising stands for the electrolytic oxidation of aluminium. As the name suggests, this process only takes place with aluminium and different aluminium alloys. The special feature of the anodised layer is its composition. In contrast to conventional aluminium electroplating, the top metal layer is converted into an oxide layer, a type of ceramic. This conversion works from the inside to the outside, which means that part of the surface is within the workpiece. The advantage is the resulting high corrosion protection that protects the aluminium. The interaction between the lightweight aluminium and the hard anodised layer creates a popular surface that is used in many applications in almost every branch of industry – above all in the automotive industry.

Another feature of the anodised layer is the colouring of workpieces made of anodisable aluminium or aluminium alloys. Different dyes are embedded in the layer during the process depending on the colour requirements. The properties of the layer do not change and the high corrosion protection is maintained.

As a specialist in the area of aluminium electroplating, we are ideally set up for the anodising process. We are able to carry out chemical and mechanical preparatory work in-house.
