Not Ranked
Typically 3003 or 1100 at .060" is used.
Forming methods:
English wheel, British Sports cars.
Hammer form (often just a tree stump), Italian sports cars of the '60s.
Power (Yoder) hammer, Kimmons Coach works (built several Cobra bodies for Shelby. Also has restored several original Cobras)
Another more modern method is superplastic forming. Panoz, Morgan and Ford GT form their bodies this way. This type of forming also requires the use of special alloys.
I do not know how the new Audi, Jaguar, and Ferrari are made. I suspect they are pressed.
Bodies are typically gas (oxy actelene or oxy hydrogen) welded together. TIG is too slow and brittle.
