Take advantage of cathodic protection materials to build a wonderful tomorrow
Cathodic Protection technology is the technology to stop or prevent the protected metal structure from electrochemical corrosion. Reasonable cathodic protection can lengthen the service life of metal structure and ensure its safe operation.
Basic introduction
Zinc anode is primarily used for corrosion prevention in seawater of steel and aluminum equipment and structures such as ship hull, ballast tank, heat exchanger, condenser, pier, pilling, etc. It can also be used as packaged anodes as grounding cells on electrical motors panels, conduits, and across insulators on pipelines to limit dangerously high voltages.

However, zinc anode is not recommended to use in freshwater. In freshwater environment, zinc can form a passive film. This film insulates the anode and stops it from protection.

Zinc anode provides the lowest driving voltage in comparison with aluminum anode and magnesium anode. Therefore, it does not easily cause overprotection which leads to coating disbondment and hydrogen damage of high strength steel.

Yuxi zinc anode conforms to ASTM B418 and U.S. Millitary Specification, MIL-A-18001K standard, high purity zinc ingot 99.995% and other high quality raw materials with rigid production and inspection procedure to ensure our zinc anode meet or excel the international standard requirement.
