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
Water heater anode rod or sacrificial anode is the important component part with only one purpose to protect metal tank from corrosion. Extruded Magnesium and Aluminum anodes have high surface and length ratios in relation to cross sectional size. This allows these anodes to deliver a greater amount of current per weight than cast anodes, therefore to deliver effective protection to structures in even highly resistive electrolytes.

YUXI supplies extruded anodes in high potential (Mg-Mn alloy), standard potential (AZ31 alloy) and Aluminum alloy as well. Our extruded and cast anodes are typically suitable for all kinds of water storage tanks or in pre-polarization of offshore structures and so on.
