Aluminum Anode

Aluminum anode is used as a part of a technique called cathodic protection (CP). The aluminum sacrificial anode is also a conductive rod that is attached to metal structures or installed into metal devices. This part is used to reduce corrosion in metal objects including buildings, structures, and home appliances like water heaters. With more than 12 years' research history and production experience, Corroco is the only researcher and manufacturer for HP and HT aluminum anodes in the world. Our high potential aluminum anode adopts exclusive technology and chemical composition. The aluminum anode can be widely applied to high-temperature area platform, oil-water separator, heat exchanger, boiler, high-temperature pipeline, etc. Aluminum sacrificial anodes have several advantages, such as lighter weight and much higher capacity than zinc anodes.
