About Our Products



What makes Optimum Anodes’ Products superior?  Compare for yourself:


OPTIMUM Cathodic Protection
Our cost-effective dimensionally stable anodes that are both reliable and cost competitive for most cathodic protection applications.


  • We supply mixed-metal-oxide (MMO) and platinum catalytic coatings that are sintered to a titanium substrate, providing an anode that is both lightweight and durable.
  • Our proprietary catalysts are suitable for use in a wide range of cathodic protection applications, including soil, carbonaceous landfill, fresh water, brackish water, and seawater.
  • Our high-value metal substrates assure advanced corrosion resistance.


OPTIMUM:  Precious Metal Coatings That Last


  • Our OptimumOxides series of precious metal oxide coatings have a primary coating of ruthenium, iridium, platinum, or palladium.
  • The primary precious metal oxide can be combined with other precious metals and/or other valve or base metal oxides to produce an MMO coating.
  • Highly efficient, robust electrochemical catalysts that can provide many years of uninterrupted service.
  • IROxide™, part of our OptimumOxides™ series, is our iridium oxide series of anode formulations whose primary precious metal, iridium, is converted into oxide for the energy-efficient production of oxygen.
  • Depending on the environment and your specific requirements, the iridium can be combined with other precious metal and/or base metal oxides to produce the optimum electrochemical catalyst for specific process conditions and the desired operating performance and product results.
  • IROxide robust coatings are formulated to withstand a range of acidic environments.
  • Our PurePlat coatings are high purity platinum that meet or exceed the industry standard and may be applied to titanium, niobium, tantalum, and other exotic substances.
  • The electro-deposited or clad-coated substrate is more cost-effective than, and mechanically superior to, pure platinum structures.
  • PurePlat coatings provide Optimum performance by varying the surface morphology to create an application- and process specific electrochemical characteristic.


Energy Efficient – OPTIMUM Cost Saving
Optimum Anodes optimize your energy consumption. 

Operating at low anodic potentials for a selected environment, the coatings selection assures the right balance of energy efficiency and life.

Additionally, the dimensional stability of Optimum Anodes maintains low energy consumption throughout the design life of the anode.
