Aluminum Aqueous Anodes

In salt water environments, where electrical resistivities are usually quite low, Aluminum anodes are the most economical choice for corrosion protection. These anodes offer higher current efficiency and lower anode consumption than both Magnesium and Zinc in aqueous saline areas, making Aluminum ideal for the protection of ship hulls on oceangoing vessels. Corrpro offers two options of bolt on, cast type III Aluminum anodes in 8 inches by 8 inches by 4 inches and 8 inches by 8 inches by 2 inches sizes. The anodes come with a 3/4-inch mounting hole, allowing you to bolt directly onto the hull or structure. Cast Aluminum anodes are available in Aluminum alloy type III. Alloy type III generates a potential of -1.10V CSE and has a current efficiency rating of 87% in free-flowing water. 

To ensure quality, each production run of these anodes is inspected for correct chemical composition through a variety of test. Electrochemical tests are also employed to verify performance characteristics.
