Aluminum can
Encyclopedia
An aluminum can, or can, is a container for packaging made primarily of aluminum (BrE Aluminium).
They are 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.

Usage

Use of aluminum in cans began in 1957. Aluminum 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 steel.

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.

The advantages of aluminum over steel (tinplate) cans include;
  • light weight
  • competitive cost
  • usage of easy-open aluminum ends: no need for a can opener
    Can opener
    A can opener is a device used to open metal cans. Although preservation of food using tin cans had been practiced since at least 1772 in the Netherlands, the first can openers were patented only in 1855 in England and in 1858 in the United States. Those openers were basically variations of a...
