The property of metal that permits it to be reduced in cross sectional area without fracture. In a tensile test, ductile metals show considerable elongation eventually failing by necking, with consequent rapid increase in local stresses. The property of metals that enables them to be mechanically deformed without fracture when cold. Ductility is usually measured by elongation and reduction of sectional area as determined in a tensile test.
