Surface Treatment

“… The thing with optics …”

Many different colours possible with anodozing

As the term already states, dimensional tolerance, i.e. low tolerances for thickness and flatness, is paramount with aluminum precision plates. These properties, combined with a visually appealing surface and good internal properties, have opened a wide range of applications for aluminum precision plates. However, this attractive appearance is all too fleeting.

Without additional surface protection, which is usually provided through various anodizing process, high-quality surfaces cannot be protected from mechanical, thermal and chemical stresses in the long run. Increasingly, the color design and thus the implementation of optical requirements are playing an important role.

Anodizing with optical requirements of cast aluminum plates can be a challenge, which is why GLEICH Aluminium has developed the G.AL C250 ELOX PLUS precision plate which sets high standards in terms of optical properties after anodizing and can be used in applications that were previously mostly limited to rolled products.


Customer Experience

With G.AL C250 ELOX PLUS, our products are setting new visual standards. Through intensive collaboration with GLEICH Aluminium, we were able to test this product and integrate it into our planning as early as in the development stage of G.AL C250 ELOX PLUS.
