Soft Iron Anode Rod

The soft iron anode is especially useful in protection against stress corrosion of copper alloys. Therefore, the soft iron anode is mostly applied to the corrosion protection of copper alloy tubes found in heat exchanger, condensers, pumps, fresh water facilities, desalination plants (evaporator, brine heater) and cooling systems of power plants. It is also used as a positive pole which has less carbon than other general irons.
