The pure metal is very reactive chemically and rapidly corrodes, especially in moist air or at elevated temperatures. It has four allotropic forms or ferrites, known as alpha, beta, gamma, and omega, with transition points at 700, 928, and 1530C.
Iron is hard, brittle, fairly fusible, and is used to produce other alloys, including steel.
Melting point: 1538 °C Boiling point: 2861 °C
