Product Details
Product Introduction
Aluminum alloy sacrificial anodes can prevent corrosion of steel structures in seawater and freshwater, suitable for ships, machinery, marine engineering, and port facilities in seawater environments, as well as for cathodic protection of metal corrosion in facilities such as seawater pipelines, hulls, pressurized chambers, storage tanks, drilling platforms, and pipelines and cables in marine mud. The performance of aluminum anodes is influenced by the chemical composition of the alloy. We provide different alloy compositions to meet customer requirements, and we can also manufacture anodes with special specifications and chemical compositions according to customer requests.
Implementation Standards
GB4948-2002
Main Functional Features
Low driving voltage, lightweight, high current efficiency.
Applicable Scope
Aluminum alloy sacrificial anodes are suitable for cathodic protection of metal corrosion in facilities such as ships, machinery, marine engineering, and port facilities in seawater environments, as well as pipelines and cables in marine mud.
