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.
The advantages of aluminum over steel (tinplated) cans include:
Usage of easy-open aluminum ends: no need for a can opener
Aluminum does not rust
Aluminum cans are often made with recycled aluminum; approximately 68% of a standard North American can is recycled aluminum. Cans are the most recycled beverage container, at a rate of 69% worldwide.
