MMO wire anodes consist of a high tensile strength pure titanium wire substrate ( ASTM B348 Grade I/II ) which is coated by an electrocatalytic film of noble metal oxide. ( IrO2/Ta2O5). The Mixed Metal Oxide ( MMO ) coating film activates the titanium allowing the combined product to act as a very effective impressed current cathodic protection ( ICCP ) anode in a variety of applications. MMO wire has excellent performance characteristics with very little wear and dissolution of the metal oxide coating.
The design life of the anode depends on the operating current in various applications from soil to seawater. The anodes are manufactured in three diameters: 1.0mm, 1.5 mm and 3.0mm. Due to the extremely low consumption rate of the coating ( measured in terms of milligrams per year ) at different current output, the projected life of the anodes varies from 15 to 50 years.
