The reason metals bend or dent when struck is linked to malleability, a physical property that is very important to chemists as well as engineers. Malleability is the ability of a substance, usually a metal, to be deformed or molded into a different shape.For chemists, the malleability of the metal gives an important means of describing the specific characteristics of a metal and relating it to the arrangement of the atoms within the metal.alleability is the ability of a substance, usually a metal, to be deformed or molded into a different shape.
