Extruded Magnesium anode rods or sacrificial anode is the important component part with only one purpose to 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 supply extruded anodes in both high potential (Mg-Mn alloy),standard potential (AZ31 alloy) and Alumnium Alloy.Our extruded anodes are typically suitable for all kinds of water storage tanks or in prepolarization of offshore structure and so on.
♦ Application :
Water heater Magnesium rod are mainly used in water heater, boiler, heat exchanger, water tank,etc.It has properties of softing water, de-dirt residual ,en-longing the working life of container.
♦ Chemical compositions Extruded Alloy Magnesium Anode Rods :
Type | Al | Zn | Mn | Fe | Cu | Ni | Si | Others | Mg |
AZ31B | 2.5-3.5 | 0.6-1.4 | 0.2-1.0 | 0.005 | 0.01 | 0.001 | 0.1 | 0.3 | Balance |
Mg-Mn | 0.01 | - | 0.5-1.3 | 0.03 | 0.02 | 0.001 | 0.05 | 0.3 | Balance |
♦ Electrochemical properties of Extruded Alloy Magnesium Rods Anodes:
Type | Open-circuit voltage (-V) | Close-circuit voltage (-V)Zn | Actual capacitance (A·h/g) | Current efficiency (%) |
