What is Aluminum Foil Made Of?
If you’ve ever used aluminum foil in your kitchen, you might have wondered what this shiny, thin material is made of.
Aluminum is a lightweight, silver-colored metal that is highly malleable and ductile.
Aluminum foil is made by rolling large slabs of aluminum into thin sheets. The process begins with bauxite, The aluminum oxide is extracted from the bauxite using a chemical process, and then it’s purified to remove impurities, leaving behind pure aluminum.
Once the aluminum has been extracted, it’s rolled into large slabs, which are then heated and rolled again and again until the metal becomes thinner and thinner. This process is called hot rolling. Eventually, the aluminum becomes thin enough to be considered aluminum foil. At this point, the foil is cooled and cut into the appropriate size for packaging.
The Composition of Aluminum Foil
Aluminum foil is made of 99.9% pure aluminum. This means that it contains no other metals or materials. The remaining 0.1% is made up of small amounts of other elements, including silicon and iron. These elements are added to the aluminum to improve its strength and durability.
