Is aluminum sheet the same as aluminum foil？

No, aluminum sheet and aluminum foil are not the same. Aluminum sheet refers to flat pieces of aluminum that are thicker and used for various applications such as construction, automotive parts, and aerospace components. On the other hand, aluminum foil is a thin, flexible sheet of aluminum typically less than 0.2 millimeters thick. It is primarily used for packaging, wrapping food, insulation, and cooking. While both aluminum sheet and aluminum foil are made from the same material, they serve different purposes due to their thickness and properties.
