The ductility and malleability are the properties of metals, this property that helps the metals to be deformed.
Ductility can be defined as the property of a material that allows it to stretch without being damaged. Metals have a ductile property that allows them to be stretched into wires. An example is copper wire. Ductile metals are formed from pulling, compression, or twisting. A metal ductility is measured by looking at its tensile strength.
Malleability refers to the ability of a metal to change its form under compressive stress. The metals having malleable property can be rolled or beaten into sheets. Examples are aluminum foil and lead. Metal malleability is measured by looking at how much pressure it can withstand without breaking.
