High Purity Sacrificial Anode Cathodic Protection 9D2-1 17 Lb Magnesium Anode
GB/T 17731-2015 High Purity Magnesium Sacrifical Anode For Corrosion Protection In Water Heater
Introduction:
They protect steel by sacrificing electrochemical action. This type of galvanic protection is called "sacrificial"; magnesium rods (anode) corrode instead of cans (cathode). This principle of electrolytic corrosion control is referred to as "cathodic protection". The tank is protected because the cathode surface does not rust. The magnesium anode rod is a very important factor in the life of the tank and should only be removed for inspection or draining.
Magnesium sacrificial anode features:
- good protection performance
- easy installation
- automatic operation after installation
- no maintenance
- no external current
- low engineering cost
- easy replacement
Magnesium alloy anode is an ideal cathodic protection method.
The electrochemical performance:
| Open voltage | Closed voltage | Actual capacity | Efficiency |
| 1.70-1.75 | 1.58-1.62 | 1230 min | 50 min |

Applications:
Magnesium alloy sacrificial anode is an ideal sacrificial anode material, suitable for soil and fresh water media, because of its negative potential, which is lower than that of steel, with extremely high electrochemical performance, uniform anode consumption, long life and large power generation per unit mass. Cathodic protection of metal structures, used in oil pipelines, natural gas pipelines, underground oil tanks, oil platforms, water heaters, etc.
