I'm in the United States, and I don't know if I've ever seen an aluminum food can here. All of the Campbells Soup Cans, Canned vegetables, etc, are in steel cans. They are usually coated with a polymer that can break down into nasty things if it's heated, though. I found that out after heating many meals in the can over a campfire.
