long service life Magnesium Anodes with Low Density protection of metal components
Long Service Life Magnesium Anodes With Low Density Protection Of Metal Components
Introduction:
Magnesium-based sacrificial anodes include pure magnesium, Mg-Mn alloys and Mg-AI-Zn-Mn alloys. Their common characteristics are low density, large theoretical capacitance, negative potential, and low polarizability. The driving voltage is very large, and it is suitable for the protection of metal components in soil and fresh water with high resistivity.
Parameters:
Our products have the following specifications:
- " D " anode
- " R " Cylindrical anode
- " S " anode

| 1.70-1.75 | 1.58-1.62 | 1230 min | 50 min |
Advantages:
A: The one-time investment cost is low, and basically no maintenance cost is required during operation
B: The utilization rate of the protection current is high, and no over-protection occurs
C: No interference to adjacent underground metal facilities, suitable for long-distance pipelines without power supply, and small-scale decentralized pipeline protection
D: It has the functions of grounding and protection
E: The construction technology is simple, and no special professional maintenance management is usually required.
Applications:
Magnesium anodes are effective and affordable in fighting corrosion. Magnesium anodes play a key role in protecting steel structures in salt and fresh water. include:
- Hull and various other boats
- Water tank
- Piers, piers and piers
- pipeline
- heat exchanger
- travel screen
