   (1958?) During WW-II they were made of steel. I remember Pepsi in steel cans   
   in the early '60s.

   Steel is a lot stronger than aluminum. OTOH, it cost more to ship. Aluminum   
   and steel cans both have an internal coating to prevent corrosion. Tomatoes   
   would quickly eat through an unlined steel can. That is why they have a thin,   
   tin plating. Hence their    
   name of 'Tin Cans'.   
   When I was stationed at Ft. Greely, Alaska in the '70s, the aluminum soda cans   
   were so thin that you could rip them apart with your bare hands. They tore   
   like a sheet of paper. They weighed about 1/3 of a regular soda can. This was   
   done, since they were    
   canned in Seattle, and trucked into Alaska. The semis could only use short   
   trailers, so shipping costs were high.
