ZAC Sacrificial Anode

It has long been history regarded Zinc as corrosion-proof metal, and the well-known thought to use this method to prevent corrosion from vessel's shell, boiler, outside of internal combustion engine. On recent 2 decades, we carry out many further studies on such material and settings. During this period, American engineer based on their own advanced technology, they start to improving the material and size. Otherwise, China continuously made achievements from the study of using Zinc as convection-current anode. After we add trace Cadmium and Aluminum in, their corrosion-proof efficiency will be better. Above all these studies are based on high-purity Zinc materials. Now, the popular method over the world to use ZAC, CPZ is the best way regarded Zinc as corrosion-proof anode.
