Effective and economical, magnesium anodes have the highest driving potential of any sacrificial anode at -1.3 volts, which is ideal for freshwater environments. A great solution for combating corrosion of head covers, channels/tubes, and other metallic surfaces in freshwater environments. Our magnesium tank anodes are created with the limited space of condensers and pencil anodes in mind, offering protection from internal corrosion.
Their electrochemical equivalent is 17 pounds per ampere year, or 500 ampere hours per pound, making them a cost-effective and high quality option.
Manufactured to meet or exceed industry standards, our zinc pencil and condenser anodes are ideal for heat transfer equipment, as well as coated steel structures with limited space. Zinc anodes can be used as a permanent reference under tanks & vessels as they are effective for prolonging a structure’s life and its coating in marine environments up to 120°F.
Due to zinc’s higher density (446lb/ft3), zinc anodes are smaller with a higher resistance to electrolytes than magnesium or aluminum anodes of the same weight. Zinc also boasts a high conversion efficiency of 90% compared to 50% for magnesium making it a cost-efficient solution. Produced to resist corrosion build-up, these zinc anodes continue to produce protective currents until they are fully depleted, meaning fewer replacements and reduction of overall costs.
