Zinc anode is a kind of zinc component used to help galvanized steel and other objects. It is often used to prevent corrosion and help other materials corrode more slowly and last longer.
The sacrificial zinc anode is also a part of a large system which gives objects corrosion resistant abilities. They are common among metallic marine applications, such as boats with metal hulls and metal crab pots.
Saltwater is very corrosive and will quickly rust the metal, unless the galvanic coupling (voltaic couple) is formed with the sacrificial zinc anode, which can greatly increasing its useful life in the water.
With high capacity, current efficiency and high machine performance, sacrificial zinc anodes are widely used in cathodic protection of tank bottom, pipeline, and water pipe in soil environments.
