The performance of aluminum anodes is influenced by the chemical composition of the alloy. We offer various alloy compositions to meet customer requirements and can design and manufacture aluminum alloy sacrificial anodes with special specifications and properties according to specific client needs.
GB/T4948-2002
Low drive voltage, lightweight, high current efficiency
Aluminum anodes prevent corrosion of steel structures in both seawater and freshwater environments.
