Rectangular Magnesium Condenser Anode

To address the applications in fresh water or aqueous environments where the electrolyte resistivity is higher, we manufacture a full product line of H-1 alloy magnesium condenser anodes, suitable for use in heat exchangers, condenser water boxes, cooling towers, intercoolers and tank interiors.

Quality Substrate Material
Constructed from high grade magnesium alloy, our condenser anode conforms to meet American standard ASTM B843 – AZ63B.

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 condenser anode is normally cast 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 condenser 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.
