As a contract service provider, we use different processes to polish aluminium to a high gloss, depending on the requirements and type of aluminium. These include mechanical polishing processes such as grinding with different grit sizes and subsequent polishing with special pastes. In some cases, electrochemical processes are also used, such as anodising, to create a protective oxide layer.

The materials used include sandpaper in different grit sizes (e.g. 240 to 2000 grit), polishing discs made of cotton, flannel or sisal, and special polishing pastes. These materials are used on polishing machines or sanding blocks to achieve optimum results.

Polishing aluminium requires experience and the right equipment to achieve a high-quality result without damage. Professional service providers can ensure that the aluminium is not overheated and that no unwanted surface damage occurs, such as scratches or scoring.

The cost of polishing aluminium depends on various factors, including the size of the aluminium part, the condition of the surface and the desired end result.

The duration of the polishing process can vary greatly. Smaller parts can be polished in a few hours, while larger or badly damaged parts can take longer. Service providers usually give an accurate time estimate when they inspect the job.

Yes, improper polishing can lead to overheating of the material, which can damage the surface structure. Inadequate removal of the oxide layer before polishing can also result in the aluminium not shining evenly and oxidising again quickly.

To maintain the shine of the aluminium in the long term, it should be cleaned regularly and, if necessary, sealed with clear lacquer or special aluminium care products. This protects the surface from oxidation and renewed soiling.
