Marine Anodes

Corrosion is a constant threat in a marine environment and Aluminum Marine anodes a vital protection against this corrosion. They are widely used to prolong the service life of commercial, private and military vessels, as well as marine structures.

Aluminum Marine anodes are used for protection in freshwater, brackish water and saltwater applications that need a “sacrificial” anode that is less resistant to the electrolytes produced in these waters. The aluminum, in essence, prevents corrosion and rust as the aluminum attracts corrosion first and dissolves over time to protect hulls and other metal parts from damage by “sacrificing” itself.

Our bar and plate anodes, available in “bolt-on” and “weld on” styles, in streamlined, semi-streamlined and teardrop formats, are specially formulated to provide superior corrosion protection of the hull and components of marine vessels and structures. Both styles use either aluminum or steel inserts. Weld-on hull anodes have projecting tabs for tack welding directly to the ship’s structure. Steel tabs (straps) are provided as standard. Aluminum tabs are available on most anodes. Popular modes and sizes are available from inventory.
