Chromium plating

We make decorative coatings from solutions of hexavalent chromium and trivalent chromium, depending on customer requirements. Chromium coatings are applied on the sub-layer of copper and nickel, and the nickel sub-layer. The thickness of the chromium coating on said sub-layers is between 0,3 - 0,5 µm. Due to the high tendency to passivation, chromium coatings are highly resistant to water and they retain their shine for a long time.
