Zinc anodes

Zinc alloy anodes are particularly suitable for ballast tanks, hull of ships, jetties and subsea pipeline applications, etc. Zinc Alloy Anode are cast from high grade zinc alloy 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.
