Aluminum Anode for Storage Tank

Aluminum Anode for Storage Tank

The most commonly used aluminum alloy anodes are Al-Zn-In series and Al-Zn-Hg series, applicable to the cathodic protection of ships, ports and marine facilities in seawater, sea water cooling system and reservoir deposited water site and other constructions.

Aluminum Zinc Indium system (AZI) sacrificial anode is cast 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.

Implementing Standard

U.S.Mil-A-1800 K/W, gb4948-2002

Main Performance

The driving voltage is low; light weight; high current efficiency.

Application

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.
