High-Efficiency Aluminum Alloy Sacrificial Anode | Premium Aluminum Anode

Main Uses of Aluminum
Over the past fifty years, aluminum has become one of the most widely used metals in the world. Wrought aluminum and aluminum alloys are aluminum castings produced by forging methods; deformed aluminum and aluminum alloys are processed aluminum products such as plates, strips, foils, tubes, bars, profiles, wires, and forgings produced by pressure processing methods.

Main Applications:
Aluminum anodes can prevent the corrosion of steel structures in seawater and freshwater, and are suitable for the cathodic protection of metals in facilities such as ships, mechanical equipment, marine engineering, and port facilities in seawater media, as well as seawater pipelines, hulls, ballast tanks, storage tanks, drilling platforms, pipelines in seabed mud, cables, and other facilities. The performance of aluminum anodes is influenced by the chemical composition of the alloy. We offer different alloy compositions to meet customer requirements and can also manufacture anodes with specific chemical compositions according to customer specifications.
