Exactly How Many Aluminum Cans Does It Take To Make A Pound?

It's around 31 - 34 cans per pound, but many people use 32 (16-oz) cans to the pound.  Modern cans weight slightly less than older cans because they're thinner and the end caps are made differently.  It used to be around 24 cans per pound.  And of course, it depends on what size they are and those last drops of soda will solidify and slightly add to their weight.

34.2 12 oz cans according to the american aluminium recyclers association. In 1980 it was 25.
