The Hanging Aluminum Anode is a hanging-type sacrificial anode cast from Al-Zn-In (Aluminum-Zinc-Indium) series aluminum alloy. Designed for internal cathodic protection of boilers, heat exchangers, seawater storage tanks, and salt-containing cooling water equipment, the anode protects carbon steel substrates from corrosion by preferentially consuming itself through electrochemical corrosion. The anode is secured via a 4” 150# hanging assembly.
