An Aluminum Alloy Sacrificial Anode is a galvanic anode used in cathodic protection (CP) systems to prevent corrosion of steel and other metallic structures. The anode operates by preferentially corroding in place of the protected structure, thereby providing continuous protective current without the need for an external power source.
