What is Magnesium anode?
Magnesium Anodes are used in the Corrosion Control industry. In a process known as Cathodic Protection, Sacrificial Anodes are connected by a cable to an underground natural gas pipe, an oil or water pipe, a propane tank or other such structure. The anode acts like a battery, giving off a low-voltage electrical current so that, over time, the anode corrodes but the structure that is being protected remains like new. Cathodic Protection using magnesium and other types of anodes prevents costly repairs and leaks. Extruded Magnesium Anodes are used to extend the life of home and commercial water heaters.
