Definition of ductility
: 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
