Zinc Hull/Tank (Flush Mount) Anode

High output zinc anodes are produced to standard alloy compositions conforming to Military Specifications MIL-A-1801 J & ASTM B-418-73, Type I. These alloys are designed to protect steel in seawater environment and contain more than 99% pure zinc.

High output zinc anodes operate at a nominal galvanic efficiency of 95% in seawater. Galvanic efficiency directly impacts anode life and performance. These anodes resist the formation of hard, dense corrosion products and continue producing protective current until complete consumption. The extended service life results in fewer replacements and reduced operating costs.

Typical Applications

Hull Anodes are designed for attachment to hulls of sea-going vessels or other flat steel surfaces. Zinc anodes are not recommended for applications where temperature is higher than 120°F. Typical applications include ship hulls, lock and dams, traveling screens, etc.

Contains single 1/4" x 1 1/2" wide steel longitudinal strap. Can be bolted or weld to hull. Particulary Suited for smaller ships coastal vessels, harbor tugs, etc. This anode has a current rating of one amp-year.
