Zinc Alloy Anode are cast from high grade zinc alloyed to ensure an even corrosion pattern, reliable electrical efficiency and long working life. The anodes are made to meet ASTM B418 type I standard and U.S. MIL-A-18001K.
zinc anode's protective properties result from a strongly negative reduction potential, which is more negative than the metal it is protecting. Oxidants, which corrode metals, will oxidize the zinc anode rather than the protected metal structure, thus preventing the structure from being corroded.
