The AT-8 Type Aluminum Anode is a specialized aluminum alloy sacrificial anode designed for the cathodic protection (CP) of water ballast tanks in marine vessels. Manufactured from Al-Zn-In alloy, this anode provides stable electrochemical performance, high current efficiency, and controlled dissolution in confined ballast tank environments.
Ballast tanks are subject to alternating wet and dry conditions, oxygen
