At least four allotropes of iron (differing atom arrangements in the solid) are known, conventionally denoted α, γ, δ, and ε. The first three forms are observed at ordinary pressures. As molten iron cools past its freezing point of 1538 °C, it crystallizes into its δ allotrope, which has a body-centered cubic (bcc) crystal structure. As it cools further to 1394 °C, it changes to its γ-iron allotrope, a face-centered cubic (f… WebbPhysical Properties of Iron. Pure iron is silvery-white, easy to work with and you can cut through using a knife. Pure iron can be hammered into sheets and drawn into wires. Despite these surprising properties, iron still conducts heat and electricity like other metals and can be magnetised. Chemical Properties. Pure iron will readily combine ...
