Profile: GaUS Anodes International, LLC specializes in the manufacture of sacrificial aluminum, zinc and magnesium anodes. Sacrificial anode is a metallic anode used in cathodic protection where it intentionally dissolves to protect other metallic components. The more active metal is more easily oxidized than the protected metal and corrodes first. We manufacture aluminum anodes with alloys of the same composition as Galvalum III. We developed GaUSALUM III and GaUSALUM III DCW with traces of indium, zinc, and silicon, producing an anode with a capacity three times over that of zinc. Our anodes are environmentally friendly and meet most accepted industry criteria. Our zinc anodes are efficient corrosion protectors in applications where temperature exposures do not exceed 120°F (50°C). They meet the mil-spec revision and are also covered by ASTM-418-95 Type I. Typical uses in deep, cold water or saline mud include ship hulls, ballast tanks, sea chests, engine rooms, pipelines, piers, docks and buoys. Our high potential anode is cast from high purity magnesium, and produces an open circuit potential of 1.70-1.75 volts using ASTM Standard G97 with respect to a saturated calomel electrode.
