Aluminium Finishes

The natural finish and surface quality of aluminium in most cases is such that it can be used for many applications without any finishing required. There are cases in which different aluminium finishes are required for different reasons which include aesthetic improvement, different colour, better resistance to wear, improved reflectivity, better surface structure and improved electrical insulation.

At thyssenkrupp, we offer many different aluminium finishes each of which has different properties and is best suited for different applications.

Aluminium Coating

Aluminium has various desirable properties making it one of the more popular metals. It is affordable and has a high strength-to-weight ratio and a high resistance to corrosion. When an additional finish is applied to the metal, the corrosion properties can be improved.

Naturally, aluminium reacts with air to produce an aluminium oxide coating on the surface of the metal that provides some resistance to corrosion. The oxide is sufficient in most cases but, in extreme environments where additional protection is required additional surface treatment can help to improve the corrosion resistance qualities of aluminium and make it more suitable to extreme applications.

Different aluminium finishes can also improve the aesthetic appearance of aluminium. Different finishes have will have different looks hence, you need to select an appropriate finish depending on your desired application.
