Extruded Magnesium Rod AZ31B Magnesium Sacrificial Alloys Round Anode Rod
Magnesium anode rod for water heater, or sacrificial anode is the important component part, for protect metal tank from corrosion. Extruded Alumnium anodes and Magnesium anodes have high current to weight ratio,are suitable to be used in where a small diameter anode is required to give enough cathodic current.
We can supply various extruded anodes in both high potential (Mg-Mn alloy),standard potential (AZ31,AZ63 alloy) and Alumnium Alloy. Our extruded anodes are widely suitable for all kinds of water storage tanks or in prepolarization of offshore structure and so on.
