Does anyone know what type of aluminium is used in the production of panel metal as used by us kitcar builders and general motorsport?

I'm guessing its either the 3000 or 5000 series aluminiums, but if anyone has any extra knowledge or links to information on the net I'd be very greatful.

Thanks,
Oli
