What materials does a car consist of?

Question

Dear Chris, I'm doing a science project on the recycling of a used car. I need to know what the percentages of materials used in producing a car.

Is it possible to obtain such information somewhere?

Regards.

Dreyer Swart.

Answer

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.
