ELECTROCHEMICAL PROPERTIES
Due to its high content of silicon, the anode surface is readily and continually oxidized with a thin film of hydrated silicon oxides, which protects the anode from metal pitting. Our high silicon cast iron anodes exhibit extraordinary corrosion resistance and low consumption rate in low-pH environment.
