MMO tubular anodes are fabricated from a high tensile strength pure titanium tubular substrate coated with a precious metal oxide. Mixed metal oxides have very low consumption rates (in mg/amp-year). At the same time, the dimensions of the titanium substrate remain constant over the life of the anode, providing consistently low electrical resistance. Whether operating in soil, freshwater or seawater, mixed metal oxide coatings exhibit high chemical stability, even in low pH environments. Unlike other impressed current anodes, MMO coatings are not affected by chlorine formation. MMO coated titanium anodes provide the longest life and highest current output of all ICCP anodes, mixed metal oxide coated titanium anodes can operate efficiently in all types of environments.
Different service life and output current requirements can be designed and produced by adjusting the coating ratio. The coating type, thickness and anode specification of MMO titanium anode can be customized. The Kelichi team provides you with the most professional custom anodes. Tell us about your application and we will recommend the most suitable coating.
Kelichi MMO anodes are ASTM B338 Class 1 or 2 coated with Iridium-Tantalum-Titanium (IrO2/Ta2O5) and are widely used in cathodic protection applications.
