What is the difference between tin foil and aluminum foil?

Tin foil and aluminum foil are both thin sheets of metal used for cooking, food storage, and other applications. However, they are made from different materials. Aluminum foil is made from aluminum, a lightweight, corrosion-resistant metal, while tin foil is made from tin, a softer, more malleable metal. Aluminum foil is more commonly used due to its durability and resistance to tearing, and it's also more cost-effective. Tin foil, on the other hand, has better heat conduction properties and is sometimes used for specific culinary purposes, but it's less common and can be more expensive.
