Coca-Cola can manufacturing

3004 is "thirty or forty percent of all the aluminum made" — one of the largest-tonnage alloys, work-hardened, lightly alloyed with manganese and magnesium.

Here's the 1060 alloy, 99.6% minimum aluminum. 1350 is 99.5%. Those are the big catenaries, the electrical conductors. 1100 is garden-variety aluminum. 3003 and 3004 for sheet metal — 3004 is basically Coca-Cola cans or beer cans. It's like thirty or forty percent of all the aluminum made. It's got one percent manganese and about one percent magnesium. It's fairly lightly alloyed but it has high strength, and it's got a lot of mechanical work in it — work hardening, for all you metallurgists out there. The 5000 series are basically very weldable marine components. Naval ships that are made out of aluminum, sailboats that have aluminum — a lot of these things want to be lightweight, so they use aluminum. The 5000 series are readily weldable, and you can usually get one hundred percent joint efficiency without much difficulty.

Used to illustrate multi-stage deep drawing plus ironing in one stroke, with five-micron die tolerances and supercomputer design.

This is how you make a Coca-Cola can. You take a circular blank of aluminum — or in Japan you take a circular blank of steel — and you have some hold-down clamps which are part of the die coming down. Then you have two other dies in between, and the two center dies come down and draw a cup. The very center die, which is separate from the intermediate die, keeps on coming down and does a second draw. So you get two of your drawing operations in one stroke.
