Rectangular Condenser Magnesium Anode

Magnesium condenser anodes in rectangular shape for high-resistivity water applications. Suitable for heat exchangers, cooling towers, and tank interiors.



We produce a comprehensive range of H-1 alloy magnesium condenser anodes tailored for environments with elevated electrolyte resistivity, ideal for diverse applications like heat exchangers, condenser water boxes, cooling towers, intercoolers, and tank interiors in freshwater or aqueous settings.

Quality Substrate Material
Our condenser anode is made from premium magnesium alloy and complies with the American standard ASTM B843 – AZ63B.

Element Content
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
Typically, our magnesium condenser anode is molded using H-1 alloy to achieve a standard potential of -1.55 volts concerning the saturated calomel electrode (SCE). Upon request, we offer high potential magnesium anodes.

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
Our magnesium condenser anode is offered with options of bare or plastisol coating. The plastisol coating acts as a highly effective shield against electrical currents, applied to the sides, ends, and faying surfaces.
