History
Foil made from a thin leaf of tin was commercially available before its aluminum counterpart. In the late 19th century and early 20th century, tin foil was in common use, and some people continue to refer to the new product by the name of the old one. Tin foil is stiffer than aluminum foil.
It tends to give a slight tin taste to food wrapped in it, which is a major reason it has largely been replaced by aluminum and other materials for wrapping food.
Because of its corrosion resistance, oxidation resistance, availability, low cost, low toxicity, and slight malleability, tin foil was used as a filling for
tooth cavities prior to the 20th century.
