Ferrous Metal is pure iron or an alloy that contains iron. It is favored for its tensile strength and durability, so is often utilized in housing construction, large-scale piping, and industrial containers. It has magnetic properties, and is, therefore, used in electrical appliances and large motors. This is especially important, as the magnetic properties of the stator, are what attract the rotor, to facilitate the proper working of the motor. Ferrous Metal can be easily made less corrosive, by adding other elements or by cathodic protection.
