Magnesium bare anode is usually made into two types with different electro-potential (relative to Cu/CuSO4 reference electrode):
- High Potential (HP) magnesium anode (-1.70V)
- Standard Potential (H-1) magnesium anode (-1.50V)
|Element||Grade ASTM B843 – M1C||Grade ASTM B843 – AZ63B|
|High Potential (HP 1.7V)||Standard Potential (H-1 1.5V)|
|Aluminum||0.01% Max.||5.3 – 6.7%|
|Zinc||—||2.5 – 3.5%|
|Manganese||0.50 – 1.30%||0.15 – 0.70%|
|Silicon||0.05% Max.||0.10% Max.|
|Copper||0.02% Max.||0.02% Max.|
|Nickel||0.001% Max.||0.002% Max.|
|Iron||0.03% Max.||0.003% Max.|
|Other Each||0.05% Max.||—|
|Others Total||0.30% Max.||0.30% Max.|
Magnesium anodes are used predominately onshore in relatively high resistivity soil and water.
More about bare magnesium anodes
Our bare magnesium anodes are available in a range of designs which are specifically crafted to offer different conductive properties and connection options to suit particular types of structures.
Hull anodes are designed to flush mount against the hulls of ships, dams, or tanks via built in steel straps, whereas drive-in anodes are designed to be driven into the ground to protect buried propane tanks or steel pylons.
We have been widely recognised by a number of industries for manufacturing and supplying high quality and efficient anodes.
