Prior to eloxal coating all parts are placed in special titanium racks. In the next step the parts are degreased in a low-alkaline cleaning bath. If required by client's specifications, additional processing steps such as alkaline etching or chemical brightening can be added. Under the influence of a DC current the ELectrolytical OXidation of ALuminum takes place in a sulfuric acid solution (electrolyte). The Al-part is arranged as the anode in the electric circuit (> anodizing). The Al-part is artificially oxidized to Al2O3. In contrast to other methods such as chrome-plating, eloxal means that the coating is created by the transformation of the base material itself. This is why we have to know the exact composition of the alloys used.

The process parameters have to be established for each individual alloy. High performance materials are anodized using a special process. Thus we are able to coat the alloy-parts with a superb decorative quality. Because of the micro porosity of eloxal surfaces, colour pigments can be incorporated as specified by our clients. In the final sealing step all colour pigments are "locked" into the eloxal coating resulting in maximum corrosion protection and ultra-violet stability.
