Magnesium Anodes

Aberdeen Foundries magnesium based anodes are designed specifically for use on specialist applications where Zinc or aluminium anodes are not suitable. In freshwater or estuaries the water resistivity may be considerably higher and a greater driving potential is required to give protection to submerged structures. You would also use magnesium in instances whereby you have to protect aluminium structures underwater such as ROVs. All of the anodes are suitable for subsea frames, drilling rigs and ROV/submersible applications where magnesium is specified or required.

We can custom design any magnesium based anode to your size and insert attachment requirements. Most Data Sheet sizes are kept in stock including rods and magnesium ribbon which can be used as an anode or for de-scaling tanks.

Magnesium Anodes are of High Purity specification, Potential - 1.5 Volts Ag/Ag Cl, Capacity 1230 Amp Hrs per Kg min and Density - 1725 kg/m3
