Proceedings:

Eloxal stands for “electrolytically oxidized aluminum”.

The anodized layer is a layer that is mainly made of aluminum oxide and is usually produced with direct current with anodic polarity.

The layer properties and the layer thickness can be controlled within narrow limits and can thus be adapted to the most diverse requirements.
The anodized layer is not applied to the aluminum surface as a foreign layer, it grows through the conversion of metallic aluminum
in alumina out of the base material. There are many different types of anodizing electrolytes.
The so-called GS process, which works with or without additives based on sulfuric acid, is usually used.

To dye:

A special feature is the coloring of the anodized layer.
For mostly decorative purposes, the porous structure of a freshly created oxide layer is used to store dyes in it
