One cubic inch of aluminum weighs 1.56 ounces. The metal sinks in water, but it is still relatively lightweight. The density of aluminum is 2.7 grams per milliliter. Aluminum is used as a metal foil, a conductor of electricity and in the construction of airplane fuselages.

Aluminum is produced from bauxite, a mineral found mostly in Australia, Guinea, Brazil, India, Russia and Surinam. Aluminum oxide is extracted from bauxite and then turned into pure aluminum through electrolyzation with cryonite, a process whereby aluminum is reduced in a solution of ions with an electric current. This process occurs at 1,742 degrees Fahrenheit.
