Aluminum Anodes for Sea Water Cooling Systems - Product Description: Our aluminum anodes effectively prevent corrosion of steel structures in seawater, widely used for anticorrosion purposes in hulls, pressure tanks, seawater pipelines, port facilities, marine engineering, drilling platforms, condensers, and pipelines in soil environments. The performance of the aluminum anodes is influenced by the alloy's chemical composition, and we offer various alloy compositions to meet customer requirements. We also manufacture special specification anodes with specific chemical compositions upon customer request. Most commonly used aluminum alloy anodes include Al-Zn-In and Al-Zn-Hg systems, suitable for cathodic protection of structures in seawater, shipyards, marine facilities, seawater cooling systems, and sedimentation areas in storage tanks. The production of aluminum alloy sacrificial anodes complies with GB4948-2002 "Aluminum-Zinc-Indium Alloy Sacrificial Anodes."
