Chrome Plating & Auxiliary Anodes


DeNora offers a wide variety of auxiliary anode solutions for hexavalent chrome.  The primary customers of hexavalent chrome, automotive and decorative fixture markets, require enhanced localized chrome deposition due to the unique size and design of the parts. DeNora’s auxiliary anodes are a perfect solution for parts with unique geometries that need precise and accurate finishing.

Mixed-Metal Oxide (MMO) coated titanium anodes are characteristically lightweight and geometrically flexible.  This assures ease of installation and quick change-over on the plating line.  Utilizing titanium structures, and custom formulated MMO coatings, the auxiliary anodes are capable of multiple refurbishments; providing a cost-effective life-span.

De Nora DSA® auxiliary anodes are designed to provide:

  • Uniform current apportionment in plating of recessed areas
  • Proper deposition of copper/nickel/chromium plating thicknesses, preventing waste from over coating (extra cost) and plating burns (poor appearance/defects)
  • Cost-effective process



In recent years, health and environmental regulations have become more stringent when concerning the use of hexavalent chromium plating baths.  As a result, many metal finishers are converting to trivalent chromium baths.  De Nora GreenChrome® anodes are being recognized as the best suited solution for almost all major chemistry supplier’s trivalent plating baths. De Nora GreenChrome® anodes are characterized by a high durability and are specifically designed to preserve the integrity of the trivalent chromium bath, by preventing its oxidation to hexavalent chromium.
