An aluminum can is a container for packaging made primarily of aluminum. It is commonly used for foods and beverages but also for products such as oil, chemicals, and other liquids. The common 12-ounce-size can weighs 15 grams when empty.
Use of aluminum in cans began in 1957. Aluminum offers 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 steel. A label is either printed directly on the side of the can or will be glued to the outside of the curved surface, indicating its contents.
Most aluminum cans are made of two pieces. The bottom and body are "drawn" or "drawn and ironed" from a flat plate or shallow cup. After filling, the can "end" is sealed onto the top of the can
