What is different between ductility and touchness?

Hi Experts !
Please explain to me what is different between ductility and touchness? Many thank.

Ductile

  • Ability of a material undergo plastic deformation under static tensile loading without rupture.
  • Measurable elongation and reduction in cross section area (%).

Touchness

  • Ability of a material to withstand bending or the application of shear stresses by impact loading without fracture.
