Why we use Steel instead of Aluminium
First, steel is stronger than aluminium for the same size and thickness. In order for aluminium alloys to be at least the same strength as steel, it has to be at least double the thickness (steel 4mm = aluminium 8mm). When that happens, weight saving is not so apparent anymore. Of course there are also exotic materials and alloys that can match the strengths of steel, but the cost are astronomically high and therefore not very cost effective to bring into mass production.
