What materials does a car consist of?

Nick - We've talked quite a lot tonight about some quite high performance alloys. We've talked about nickel-based superalloys, and these are quite expensive materials. Cars want to be a bit cheaper, we want to be able to afford them from our own pockets so we quite often use more common alloys such as the steels, so iron based alloys, or aluminium alloys which are a little bit cheaper, due to their cheaper raw materials.
