Aluminum Anode for Ballast Water Tank


Aluminum Anode for Ballast Water Tank


Aluminum alloy sacrificial anode is used for the metal anti-corrosion cathodic protection of ships, mechanical equipment, offshore engineering and port facilities in seawater as well as the protection of pipes, cables and other facilities in mud.

Aluminum zinc indium system (AZI) sacrificial anode is casted by high purity aluminum, zinc, indium and other metal alloy. Aluminum alloy anode is produced in line with the implementation of GB4948-2002 Aluminum Zinc Indium Alloy Sacrificial Anode

The performance of aluminum anode is influenced by the chemical composition of the alloy, so we offer different composition of aluminum alloys to meet our customer requirements.
