Are tin cans still used? I was under the impression they'd been replaced by aluminum...
- mrob 7y agoHere in the UK, most food cans are steel. I checked several with a magnet, and the only ones that didn't stick were sardine cans. All the cylindrical food cans stuck. But canned drinks are usually aluminum.

- simonh 7y agoAluminium (sorry, Brit) is lighter than steel but more expensive, so food cans are usually steel because the contents are fairly heavy anyway. Drinks cans are smaller with a lighter contents weight, and are often held in the hand while drunk so weight is a bigger issue.
