Aluminum Anode for Harbor and Marine Engineering Facilities

Aluminum Anode for Harbor and Marine Engineering Facilities

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 construtures.

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 implementaion of GB4948-2002 Aluminum Zinc Indium Alloy Sacrificial Anode.

The aluminum alloy can prevent the corrosion of steel structure in seawater, widely used for the anti-corrosion of the ship hull, pressurized water tank, seawater pipeline, port and terminal facilities, marine engineering, drilling platform, condensator and pipelines in soil. 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.
