Rectangular Magnesium Hull Anode with Double Straps
Magnesium hull anode is commonly used for corrosion prevention on steel hull service boats in fresh water such as river boats, canal boats, cruising boats, etc. It is the best choice for fighting corrosion problems caused by stray current or pollution in freshwater. This magnesium hull anode with two cast-in galvanized steel straps can be either bolted or welded directly to a submerged structure.

Quality Substrate Material
Constructed from high grade magnesium alloy, our magnesium hull anode conforms to meet American standard ASTM B843 – AZ63C.
| Element | Contnet |
| Aluminum (Al) | 5.3% ~ 6.7% |
| Manganese (Mn) | 0.15% ~0.7% |
| Zinc (Zn) | 2.5% ~3.5% |
| Silicon (Si) | 0.1% max. |
| Copper (Cu) | 0.02% max. |
| Iron (Fe) | 0.03% max. |
| Nickel (Ni) | 0.02% max. |
| Other Impurity (each) | 0.05% max. |
| Total Impurities | 0.03% max. |
| Magnesium (Mg) | Remainder |
Custom-made Electro-potential Options
Our magnesium hull anode is normally pressure diecasted with H-1 alloy for standard potential of -1.55 volts relative to saturated calomel electrode(SCE). High potential magnesium anode is available upon request.
| Technical Measurement | Performance |
| Open Circuit Potential (-V) | 1.5 ~ 1.55 |
| Close Circuit Potential (-V) | 1.45 ~ 1.5 |
| Min. Current Capacity | 550 A.h/lbs (1230 A.h/kg) |
| Current Efficiency | 55% min. |
Optional Plastisol Coating
Magnesium hull anode is available as either bare or plastisol coated. The plastisol (polyvinyl chloride) coating on the sides, ends, and faying surfaces serves as an excellent current barrier shield —— designed to be cut away from the anode as needed for adjusting surface area contact and current output.
Parameters
All weights and dimensions are subject to normal variations in material densities. A range of standard magnesium anodes are illustrated above, custom-made configurations are available upon request.
