are soda cans made out of aluminum or tin and how can you tell the difference?
No and you will not need to be able to tell the difference since tin cans are long goneNo cans currently in wide use are composed primarily or wholly of tin; that term rather reflects the near-exclusive use in cans, until the second half of the 20th century, of tinplate steel, which combined the physical strength and relatively low price of steel with the corrosion resistance of tinUse of aluminium in cans began in the 1960sAluminium is less costly than tin-plated steel but offers the same resistance to corrosion in addition to greater malleability, resulting in ease of manufacture; this gave rise to the two-piece can, where all but the top of the can is simply stamped out of a single piece of aluminium, rather than laboriously constructed from two pieces of steelOften the top is tin-plated steel and the rest of the can aluminiumA can usually has a printed paper or plastic label glued to the outside of the curved surface, indicating its contentsA label can also be printed directly onto the metal.
