What are the differences between aluminum foil and aluminum sheet?

Aluminum foil and aluminum sheet are both made from aluminum but differ in thickness and usage. Aluminum foil is very thin, typically ranging from 0.0005 to 0.1 inches, and is used for food packaging, cooking, and insulation. It is lightweight, flexible, and has excellent barrier properties against light, air, and moisture. Aluminum sheet, on the other hand, is thicker, usually from 0.2 to 2 inches, and is used in construction, automotive, and aerospace industries due to its strength and durability. It is less flexible than foil but offers greater rigidity and can withstand higher temperatures and pressures.
