Uses of Aluminum
Aluminum is considered a “critical mineral” in domestic metallurgical applications that serve aerospace, defense, energy, and transportation technologies (Fortier and others, 2018). Aluminum, as alum, has been used by humans since at least the ancient Greek civilization. Scientists were not able to isolate it as an element until 1824. Aluminum is an extremely useful material. It has applications in all sectors of the economy. Many household items are produced with aluminum, including aluminum foil, food and drink packaging cans, and cooking utensils. Aluminum is also used to construct window frames, doors, and for roofing and siding. Aluminum’s low density make it desirable in the transportation industry for bicycles, cars, and aircraft. It is critical to the aerospace industry. Aluminum is also used for electronics and technology.
