“During the anodizing process, an oxide layer is formed on the surface of the part, which protects it against corrosion, gives it a durable surface layer, and increases its wear resistance.”

Most aluminium alloys are typically suitable for anodizing. Pieces of varying sizes, such as large sheets and long profiles, as well as small machined or laser-cut parts, are well-suited for anodizing.

Anodizing takes place through suspension processing on an automatic coating line. The anodizing line is based on a sulfuric acid-based process. Anodizing provides excellent corrosion protection and a beautiful surface for the parts. The surface is hard and highly resistant to wear. Anodized surfaces maintain their stylish appearance for decades. Typically, the material treated is aluminium. The formed oxide layer on the surface can be left in its natural colour or dyed black.

Due to the uniformity of the anodized layer, this treatment is particularly suitable for spun surfaces and parts with complex shapes. The surface withstands corrosion well, and when oxidized, it might lighten in certain spots, unlike rusting iron. Shaped aluminium parts can be anodized to provide the required wear resistance and appearance needed in applications like vehicles, sports equipment, or the electronics industry.

If there are areas on a part (such as threads or grounding points) which are not to be coated, we protect those areas using various masking techniques.

We handle products according to the ISO 7599 standard and the MET 2007 terms and conditions for surface treatment of metals.
