According to the Australian Aluminum Council, in 2001 the average aluminum can weighed 14.9 grams, which is about half an ounce. This means it takes roughly 32 empty aluminum cans to equal one pound.
Aluminum cans were first utilized by the Coors brewing company in 1959. These early cans weighed close to 3 ounces, which is around six times heavier than they are today, according to data from The Aluminum Association.
Coors was also a pioneer in aluminum can recycling, paying one cent for each can that was returned to the brewery. Today, aluminum cans are the most recycled beverage container, with the average can containing about 68 percent recycled metal.
