Iron is cheaper if you look at iron and aluminum as pure raw materials.
The reason is that aluminum is more common, but the process of refining aluminum is more complicated than iron, which makes aluminum more expensive.

The process of extracting iron from iron ore is very simple.
Aluminium has a very complicated process of extracting aluminum metal from bauxite, which is a gemstone of aluminium.
So aluminum becomes more expensive.
