Malleability is a physical property of metals and metal alloys, or generally of any kind of matter. A malleable metal can easily be deformed, especially by hammering or rolling. Malleability is an important issue in, for example, stamping and form pressing materials such as metals and plastics.
Malleability shows how mobile particles involved in metallic bonding can be pushed or pulled past each other, making metals malleable and ductile.
Gold is the most malleable metal, followed by aluminium.
