Copper Cored MMO Wire Anode

Jennings Anodes provides copper cored MMO wire anodes upon request. With electrical-conductive mixed metal oxide coating, the titanium wire is activated and functioned as anode. Copper cored MMO wire anodes has excellent performance characteristics with very little wear and dissolution of the metal oxide coating. A low consumption rate of the electrocatalytic layer operating at recommended current densities for CP applications enables a product lifetime of over 20 years in underground, brackish, seawater and concrete environments. Delivering a superior, reliable product to our clients for many years with a production capacity of 1,000,000 meters per year.

Quality Substrate Material

The high purity copper cored titanium wire has proven excellent chemical corrosion resistance, low electrical resistance, and high mechanical integrity against damage.

Noble Metal Oxide Coating

The noble metal film of the anode used depends on the operating environment. In soil or fresh water where there is either no chloride ions or low chloride ions present, therefore the Ir–Ta mixed metal oxide catalyst is recommended. For brackish and seawater, the Ir-Ru mixed metal oxide catalyst is recommended.

Low Coating Wear Rate

Stringent quality control procedures are followed throughout the coating process to ensure appropriate thickness and adhesion. Each batch is subject to thorough testing including accelerated life testing and coating thickness verification with X-ray among other tests.

Flexibility of Use

The lightweight and malleability of copper cored MMO wire anodes allow for adaptability in creating more complex configurations. They provide high conductivity, resulting in better current distribution along the entire length of the wire.
