Is aluminum foil the same as aluminum?
Aluminum foil, or tin foil, is a paper-thin, shiny sheet of aluminum metal. It’s made by rolling large slabs of aluminum until they are less than 0.2 mm thick. People may also use aluminum foil to wrap and protect more delicate foods, like vegetables, when grilling them.
Is 100% aluminum foil a pure element?
Is 100 aluminum foil a pure element? Aluminum cannot be even decomposed (separated by chemical methods) in two or more elemental substances (or elements), thus it is also an element. Ordinary foil is pure aluminum.
What other metals are in aluminum foil?
Aluminum foils are available in various alloys Pure aluminum (i.e., 100%) does not exist on the market, but other metals and semimetals are bonded to the aluminum in an alloy. These are mainly chromium, copper, iron, magnesium, manganese, silicon, titanium and zinc.
What is aluminum foil coated with?

When aluminum foil exposed to certain foods, it has been shown to leach a portion of its metallic compounds into the food, and then you eat it.
Why is bauxite used in aluminum foil?
Bauxite is refined to make a pure aluminum oxide call alumina. The alumina is charged with an electrical current. This process is known as electrolytic reduction. In recent years it has become popular to add a variety of aluminum alloys engineered to add strength and reduce the thickness of the aluminum foil.
