AUE magnesium anodes are manufactured from high-purity magnesium ingots using advanced casting technology, strictly complying with ASTM international standards. We offer two types with different electrochemical potentials—High Potential (HP) and Standard Potential (H-1)—to meet cathodic protection requirements in diverse environments. With a minimum current efficiency of 50%, our magnesium anodes serve as a cost-effective anti-corrosion solution for buried structures.
