Square Magnesium Condenser Anode

Square Magnesium Condenser Anode: Ideal for aqueous environments, suits heat exchangers, cooling towers, and tank interiors.



Our complete range of H-1 alloy magnesium condenser anodes is designed for freshwater or aqueous environments with higher resistivity. Perfect for heat exchangers, cooling towers, and tank interiors.

Quality Substrate Material
Made from premium magnesium alloy, our condenser anode meets the stringent American standard ASTM B843 – AZ63C.

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.

Custom-made Electro-potential Options
Typically, our magnesium condenser anode is manufactured using H-1 alloy to achieve a standard potential of -1.55 volts compared to the saturated calomel electrode (SCE). We also offer high potential magnesium anodes 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
You can choose our magnesium condenser anode in either bare or plastisol-coated options. The plastisol coating acts as an effective barrier against electrical currents on all surfaces.

Strict Quality Control
Our magnesium condenser anode adheres to ISO 9001:2015 standards, ensuring rigorous manufacturing, inspection, and testing processes to maintain superior quality.

Customized Configurations
The standard sizes listed are stocked at Keeper Anodes warehouse. Leveraging over five decades of production expertise, we offer tailored anode shapes, sizes, and longevity to suit your unique requirements upon inquiry.
