The typical empty soda can weighs approximately 15 grams or a half ounce. As of 2014, the weight of aluminum cans has decreased over the past few decades.
In 1992, the average weight of an aluminum can was about 16.5 grams. Through the years, aluminum cans have become lighter due to the use of less metal. Changes in the technology of processing metal has led to the availability of materials that are thinner yet stronger.
Aluminum has been used to make cans since 1957. In addition to use for canned foods and beverages, aluminum cans also are able to hold oil and other chemicals. Most aluminum cans are from recycled materials. Aluminum is ideal because of its weight, strength and pliability. Because aluminum does not corrode, it is suitable for long-term storage.
