Chrome Plating & Auxiliary Anodes


De Nora DSA® anodes are used as auxiliary anode in hexavalent chromium plating, allowing precise and accurate finishing in specialized geometries.  Such parts require an enhanced localized deposition, especially in the automotive and decorative fixture marketplace.

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 your auxiliary anodes are capable of multiple refurbishments; encompassing 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.
