: the quality or state of being ductile especially : the ability of a material to have its shape changed (as by being drawn out into wire or thread) without losing strength or breaking When certain alloys are added to metal, hardness and strength can be improved without decreasing the ductility. — Daniel A. Brandt.

What ductility means?

Ductility is the ability of a material to be drawn or plastically deformed without fracture.

Where do you see examples of ductility?

Materials that have relatively large plastic regions under tensile stress are known as ductile . Examples of ductile materials include aluminum and copper.
