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. Besides, magnesium anode is difficult to form effective protective film on the magnesium surface. In water medium, the protective film is easy to dissolve, and the magnesium self-corrosion is quite strong. Our magnesium sacrificial anode includes pure magnesium, Mg-Mn series alloy and Mg-Al-Zn-Mn series alloy.

Application of Magnesium Sacrificial Anode:
The magnesium anode is characterized by small density, big theory electric capacity, low potential negative polarization rate and large driving voltage for iron and steel (> 0.6 V). Magnesium sacrificial anode is suitable for the protection of metal components in soil and water, where the electrical resistivity is higher. Our magnesium anode is mainly used for anticorrosion of buried pipelines, onshore platforms, huge boilers and steel structures.
