    Magnesium anode is a common sacrificial anode material used in electrochemical cathodic protection engineering. This galvanic anode is connected to steel structures to prevent or slow down rusting. This magnesium sacrificial anode has high chemical activity, its electrode potential is rather negative, and the driving voltage is quite high.

    Magnesium anode is the most common material used as sacrificial anode in cathodic protection system because of its higher driving voltage, easy installation and limited maintenance. It is typically used for buried transmission oil&gas pipelines, and also can be used to protect structures in fresh water.

    High Potential Magnesium provides excellent cathodic protection in low resistivity soil conditions. They are recommended for applications where soil resistivity is more than 2,000 ohm-cm, and less than 10,000 ohm-cm. If soil resistivity is above 10,000 ohm-cm, BK recommends an impressed current system.
