So far as durability goes, aluminum beats iron in only one category. Iron oxidizes readily...so does aluminum but, the difference is that aluminum forms an oxide layer that is impermeable to oxygen. When iron rusts, the rust offers no protection and the metal continues to oxidize. Stainless steel is an iron alloy that is protected from oxidation because the chromium in the mixture provides a protective oxide layer, like aluminum's.

They are simply different elements, look at a Periodic Table. The elements are defined by the number of protons they have. Aluminum has 13 protons, Iron has 26 protons.

A better question would be what is steel? Steel is an alloywhich contains both iron and other elements, such as aluminum.

It doesn't, really.

Iron rusts; aluminum is a "self-protecting" metal which rapidly forms a (thin, essentially transparent) protective layer, which might be what you're thinking of.

Aluminium is best because it is easily bent into shapes and melted

It takes very much more energy to convert Bauxite (aluminum ore) into aluminum metal than it does to melt iron out of iron ore. The process is much more complicated too.

Suggest why aluminium is more expensive than iron?

Aluminium is more expensive than iron because of its lower abundance in the Earth's crust. It is also more costly to extract and refine aluminium due to the energy-intensive process of electrolysis. Additionally, aluminium has a higher demand and is used in a wide range of industries which further contributes to its higher price.
