One metal that forms one twelfth of the earth's crust is aluminum. Aluminum is the most abundant metal in the earth's crust, making up about 8.2% of the crust by weight. It is a versatile and lightweight metal that is commonly used in various industries such as construction, transportation, aerospace, and packaging.

Aluminum is known for its high strength-to-weight ratio, corrosion resistance, and recyclability. It is often used in the production of aircraft, automobiles, and building materials due to its durability and malleability. In addition, aluminum is commonly used in food and beverage packaging because it is non-toxic and impermeable to light, air, and moisture.

Despite its abundance in the earth's crust, aluminum is not found in its pure form in nature. Instead, it is typically found in bauxite ore, which is mined and processed to extract the aluminum metal. The process of extracting aluminum from bauxite ore involves several steps, including crushing, grinding, and refining.

Aluminum is a highly sustainable metal, as it can be recycled indefinitely without losing its properties. Recycling aluminum requires only 5% of the energy needed to produce new aluminum from bauxite ore, making it an environmentally friendly option for many industries.

If you would like to learn more about aluminum and its properties, you can visit the website of the Aluminum Association at https://www.aluminum.org/. The Aluminum Association is a trade association that represents the aluminum industry in the United States and provides information on the benefits and uses of aluminum.

In conclusion, aluminum is a metal that forms one twelfth of the earth's crust and is widely used in various industries due to its versatility and sustainability. Its abundance and recyclability make it a popular choice for many applications, from transportation to packaging.
