Although the general aluminum alloy anode can play a role in such an environment, the high temperature will accelerate the consumption of the anode, making the aluminum alloy anode unable to fully play its role. The use of heat-resistant aluminum alloy anodes can effectively alleviate this situation. The high temperature resistant aluminum anode is made of high quality raw materials and fine processing, which can adapt to various high temperature environments, and can give full play to its characteristics and provide effective cathodic protection. Cathodic protection against metal corrosion for ships in seawater medium, corrosion of steel structure in seawater, machinery and equipment, Marine engineering and port facilities, and seawater pipelines in sea mud, port terminal facilities, Marine engineering, drilling platforms, condensers and pipelines and cables in soil medium, etc.
