Use of aluminium in cars

[Marcie]

Hey,

I have to make an economic paper about the use of aluminium in the cars. (Like in the Audi A2)

Which kind of aluminium is used? Why is it used?
How do the join it with the other parts? Which aluminium-joint is use... All this questions and many others, should have been answered!

I hope you can help.

Greetings,
Marc

This seems like a very broad subject. Which part of the car are you focusing on? Frame pieces are more than likely structural and welded together, sheet metal piece would of course be formed and screwed on and engine blocks are cast and bolted on. Material grades are chosen for their corrosion resistance, strength, formidability, etc... You will have a lot of research to do if you cover the entire car. Tommy
