Passivation / Chromating

The addition of Chromium(VI) in passivation solutions for stainless steel is exclusively used to heighten the reactivity. The passivation process encourages formation of a natural oxide layer on the stainless steel, which consist of a protective layer of Chromium(III)-oxide. The finished steel surfaces therefore do not contain any Chromium(VI).

For the chromating of aluminium and aluminium alloys we can offer Chromium(VI)-free alternatives upon request.

Hard chrome plating

Our hard chrome processes are based on an electrolyte containing Chromium(VI). During the process, however, a layer of elementary Chromium is deposited on the parts. Absolutely no Chromium(VI) is contained in the finished surface.

We are a member of the CTAC2-consortium and are therefore actively engaged in the process of obtaining further authorization to use Chromium(VI) in functional hard chrome plating.

Training and Career

It is very important to us to share our knowledge and competence with the next generations. For this purpose we regularly offer trainee positions.
