High potential Magnesium Cast Anodes are a great option when high driving potential is required. The cast anodes are designed with the ability in mind to connect directly onto the structure with minimal additional items. High potential magnesium anodes have a nominal corrosion potential of -1.75V when referenced to a Copper-copper sulfate reference electrode.
These cast anodes are cast in hydraulically operated water-cooled moulds. The method of casting developed by present management in early 1980 and adopted by European and North American anode manufacturers reduces air and lead oxide entrapment. The design of the moulds has been further developed to ensure optimum bonding of the lead to the copper hanger bar. Periodic destructive tests are done on random cast anodes to ensure maximum conductivity between the copper and lead. These tests have been verified by an independent laboratory.
