Because iron is more reactive than copper. So, it is used to displace copper.

It has to do with the reactivity of Fe, it displaces Cu from d compound CuSO4, unlike Na, which is less reactive. And reactivity is a function of what I will term "electrochemical positioning".

Fe has great affinity to the sulphate ion that shows Fe replaces the copper ion the formation of compound FeSo4 or cu can be separated.

Iron oxidation state is two so iron accept sulphate ion according to mechanism.
