It's because iron (Fe) has a lot of space in it's valence shell (outer shell of electrons)
Explanation:
Electrons transfer from one atom to another via the outer shell. When there is no room in an outer shell because the outer shell is filed, such as with something like sodium (Na), electrons can't easily transfer and the material is known as an insulator.
On the other hand, when that outer shell is not filled, electrons can move freely and easily from one atom to another. Elements in the middle of the Periodic Table have this characteristic and are known as conductors.
