Question

Copper and Al are highly ductile compared
to iron.why ? ​

Answer 1

Answer:

There is no comparison possible among Cu, Al & mild steel. However, Cu & Al are both FCC metals & hence both have good ductility, but Cuscores over Al. Mild steel is strong compared to either Cu or Al , but can not give as much ductility as one can get in Cu & Al.

Answer 2

iron is relatively less ductile because of its various properties as if you heat iron in its molten state it is really flexible and hence wires cannot be drawn from such iron and if it is in alloy form then it is super hard.

iron is a good conductor or electricity hence no use of making such wires which are not shock proof.
