Aluminum Anode – 8" x 8" x 4"

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 an entire line of hull anodes made of two alloys. Alloy Type 3 generates a potential of 1.10, and has a lower current efficiency rating of 87% in free-flowing water. This anode material also performs better in saline mud and lower-chloride water. Because Alloy Type 3 has a more powerful driving voltage, fewer anodes are necessary to protect a given structure when elongated shapes are employed.

Hull anodes are molded with tapered ends to minimize water turbulence. To ensure quality, each production run of these anodes is inspected for correct chemical compostion through a variety of tests. Electrochemical tests are also employed to verify performance characteristics.

This Galv III anode is ideal for corrosion control in aggressive environments. The 8"" x 8"" x 4"" body includes a centrally mounted ¾"" coupling, allowing for easy attachment to grounding rods, equipment, or pipeline structures.
