Aluminium forms a coating of Al oxide which is a hard layer and prevents further rusting of Aluminium.

With iron the layer of iron oxide formed is flaky and cannot prevent the layer beneath from corroding further.

This can be explain by the fact that aluminum forms a non-porous, very thin tightly adhering protective oxide(Al2O3)on its surface and this film does not permit corrosion to occur.
