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. It’s used industrially for a variety of purposes, including packing, insulation and transportation.
Is aluminum foil the same as aluminum? The term “tin foil” survives in the English language as a term for the newer aluminium foil.

What type of aluminum is used for aluminum foil? The alumina is charged with an electrical current. This process is known as electrolytic reduction. The metal produced from this process is added to a wide variety of alloys allowing them to provide specific characteristics suited for a variety of applications. Aluminum foil manufacturers commonly use pure aluminum.
What other metals are in aluminum foil? Aluminum foil is characterized by its alloy and the material state. 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.
