Magnesium Tank Anode With Cylindrical Design and Pipe Insert

Protect marine vessels from corrosion with our Cylindrical Magnesium Tank Anode. Ideal for steel hulls in freshwater, it offers high driving voltage and rapid polarization.


Magnesium hull anodes are extensively employed to combat corrosion on steel hull service vessels in freshwater environments like river boats, canal boats, and cruising boats. They excel in addressing corrosion issues due to stray current or pollution, offering rapid polarization for underwater metal protection.

Quality Substrate Material
Crafted from premium magnesium alloy, our magnesium hull anode is designed to meet the rigorous American standard ASTM B843 – AZ63C.

Custom-made Electro-potential Options
Our magnesium hull anode is typically manufactured using the H-1 alloy through pressure die casting, providing a standard potential of -1.55 volts relative to the saturated calomel electrode (SCE). Customers can request high potential magnesium anodes as needed.

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
The magnesium hull anode is offered with options of being uncoated or coated with plastisol. The plastisol coating acts as a highly effective shield against electrical currents, strategically applied to allow adjustment of surface contact and current output by trimming as necessary.

Strict Quality Control
Our magnesium hull anode undergoes rigorous manufacturing, inspection, and testing processes in compliance with ISO 9001:2015 standards, ensuring top-notch quality and adherence to strict protocols.

Customized Configurations
The weights and dimensions of our magnesium anodes may vary slightly due to material densities. While we offer a range of standard configurations, we also provide custom options to meet specific requirements upon request.
