Aluminum foil demonstrates the ability of aluminum to be compressed into thin, flat sheets. Vital to its performance is resistance to tearing in this form.

Definition: While ductility is the property of a material to strain without rupturing under tension, malleability describes the ability to do so under compression. The most typical example given is that a malleable material can be pounded into thin and flat sheets without tearing. Most malleable materials are also ductile, though lead is one exception. Gold leaf and aluminum foil are common products demonstrating malleability.
