Description of Mixed Metal Oxide Titanium Wire Anode
Mixed Metal Oxide Anodes (MMO Anodes), also called dimensionally stable anodes, are a type of impressed current protection anode that consists of rare earth oxide coated onto titanium substrate. MMO coating has a low consumption rate, make the metal dimensions remain constant during the working life of the anode, which provides a consistently low resistance anode. It is usually used in environments such as seawater, brackish water, fresh water, carbon backfill, and concrete.
Advantages
- Strong resistance in conditions impacted by both oxygen and chlorine
- Various product compositions available depending on the application
- Excellent resistance in acidic media
- Durability
