(Somewhat off-topic, but I feel its worthwhile to correct mis-information 
ASAP.)

Aluminum cans are NOT produced by extrusion from a "slug" but by 
deep-drawing from a thin sheet of aluminum.

Alcoa Corp, the largest producer of aluminum in North America, has a 
detailed description of the aluminum can fabrication process at: 
https://www.alcoa.com/rigid_packaging/en/about/making_cans.asp

Also, beverage cans (soda, beer, etc) are the only ones commonly made from 
aluminum; paint, shaving cream, etc are made of steel.
