Malleable metals. Malleability is a physical property of matter, usually metals. This property usually applies to the family groups 1 to 12 on the Modern Periodic Table of Elements. It is the ability of a solid to bend or be hammered into other shapes without breaking. Examples of malleable metals are gold, iron, copper (to a degree) and lead. Malleability is the ability of a metal to be hammered into thin sheets. Gold and silver are highly malleable.
Brittleness is the property of a metal that allows little bending or deformation without shattering. In other words, a brittle metal is apt to break or crack without change of shape. Because structural metals are often subjected to shock loads, brittleness is not a very desirable property. Cast iron, cast aluminum, and very hard steel are brittle metals. Malleability. A metal that can be hammered, rolled, or pressed into various shapes without cracking or breaking or other detrimental effects is said to be malleable. This property is necessary in sheet metal that is to be worked into curved shapes such as cowlings, fairings, and wing tips. Copper is one example of a malleable metal. Ductility
