Ductile Definition

Ductility is a physical property of a material associated with the ability to be hammered thin or stretched into wire without breaking. A ductile substance can be drawn into a wire.

Examples: Most metals are good examples of ductile materials, including gold, silver, copper, erbium, terbium, and samarium. An example of a metal that is not very ductile is aluminum. Nonmetals are not generally ductile.
