Alpha iron or ferrite becomes magnetic once its temperature drops below 770 °C. The phase between 770 and 911 °C was known as beta iron before and the two phases are separated by the A2 line in the iron-carbon equilibrium diagram. Steel and cast iron. Pure iron has many undesirable properties that make it unfit for most applications.
