A Ship Hull Aluminum Anode is a sacrificial anode used in cathodic protection (CP) systems to protect the external steel surfaces of ship hulls from corrosion in marine environments. The aluminum anode corrodes preferentially, supplying protective current to the hull and preventing deterioration caused by seawater exposure.
