Marine zinc anode, double iron foot

Zinc anode is a material that is protected against corrosion by cathodic protection. It is also classified as an electrochemical anode, and other sacrificial anodes include zinc alloy and magnesium alloy sacrificial anodes. The protective properties of zinc anodes benefit from a strong negative reduction potential, which is more negative than the metal it protects. The oxidizing agent that corrodes the metal will sacrifice the anode of the zinc oxide alloy instead of the metal being protected, thus preventing the structure from corroding. Zinc alloy sacrificial anodes are commonly used in saltwater and are most commonly used in Marine applications such as hull, tank, rudder and dock. They are also commonly used in underground storage tanks and pipes.
