stretched into a wire
ductility is a material's ability to deform under tensile stress. this is often characterized by the material's ability to be stretched into a wire. ductility is especially important in metalworking because materials that crack or break under stress cannot be hammered, rolled, or drawn (drawing is a process that uses tensile forces to stretch metal).









































copper has a higher ductility than alternate metal conductors with the exception of gold and silver. because of copper’s high ductility, it is easy to draw down to diameters with very close tolerances.

ductility is defined as ‘‘an extent to which a material can sustain plastic deformation without rupture.’’ it is not only required in the forming process but is also needed for plastic redistribution of stress in members and connections, where stress concentration would occur. the ductility criteria and performance of low-ductility steels for cold-formed members and connections have been studied by dhalla, winter, and errera at cornell university. it was found that the ductility measurement in a standard tension test includes local ductility and uniform ductility. local ductility is designated as the localized elongation at the eventual fracture zone. uniform ductility is the ability of a tension coupon to undergo sizeable plastic deformations along its entire length prior to necking. this study also revealed that for the different ductility steels investigated, the elongation in 2-in. (50.8-mm) gage length did not correlate satisfactorily with either the local or the uniform ductility of the material. in order to be able to redistribute the stresses in the plastic range to avoid premature brittle fracture and to achieve full net-section strength in a tension member with stress concentrations, it is suggested that:
