Aluminum foil has many physical properties. For example, it has a ductility of around 300 MPa, so it is not very ductile. On the other hand it is very malleable and can be formed into many things. Like a tin foil ball or being shaped around food or other items. It does no fare well under tensile strength, or stretching, but it can withstand high amounts of compressive strength. In fact, aluminum foil, is basically a sheet of aluminum under compressive strength to make it thin and malleable. In addition to malleability it is also formable, meaning it can be formed or molded around and shaped into different forms.
