Extruded 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 supply extruded anodes in both high potential (Mg-Mn alloy), standard potential (AZ31 alloy) and Aluminum Alloy. Our extruded anodes are typically suitable for all kinds of water heaters and water storage tanks, or in prepolarization of offshore structure etc.
