CorrTech Tubular anodes are titanium tubes with a mixed metal oxide coating. The mixed metal oxide is a crystalline, electrically conductive coating that activates the titanium and enables it to function as an anode.
The mixed metal oxide anode has an extremely low consumption rate, measured in terms of milligrams per ampere-year. As a result of this low consumption rate, the tubular dimensions remain nearly constant during the life of the anode - providing a consistently low resistance anode. 
Whether operating in soil, freshwater, mud, or seawater, CorrTech mixed metal oxide coatings demonstrate very high chemical stability -even in environments with very low pH values. Unlike other impressed current anodes, the CorrTech coatings are not affected by the generation of chlorine.
