The MG-22 Magnesium Alloy Anode is a high-performance sacrificial (galvanic) anode designed for cathodic protection (CP) of buried and submerged steel structures, especially in high-resistivity soils and freshwater environments. It is manufactured from a magnesium-based alloy with optimized composition to provide high driving voltage, stable current output, and uniform consumption.
