An Extruded Magnesium Anode Rod is a cylindrical sacrificial (galvanic) anode manufactured through an extrusion process, designed for cathodic protection (CP) of metallic structures in soil, freshwater, or low-resistivity environments. The extrusion process ensures a dense, uniform microstructure, resulting in stable electrochemical performance and consistent corrosion behavior.
