Performance Metals

Performance Metals is the pioneer of Navalloy aluminum anodes, the only sacrificial anodes engineered to work effectively in all water types—fresh, brackish, and salt. Their patented alloy includes a trace of Indium to prevent oxide buildup, providing 30-50% longer life and a higher protection voltage than traditional zinc anodes. Navalloy is also more environmentally friendly, as it is cadmium-free and does not pollute marinas with toxic heavy metals. At Freeport Marine Supply, we carry Performance Metals anodes to give your hull, shaft, and engine the best possible cathodic protection with a "one-anode-fits-all" solution.
