1) Metal forming 
Formability is the ability of a given metal workpiece to undergo plastic deformation without being damaged. The plastic deformation capacity of metallic materials, however, is limited to a certain extent, at which point, the material could experience tearing or fracture (breakage). Processes affected by the formability of a material include: rolli...
The relative ease with which a metal can be shaped through plastic deformation.
the capacity of a material, as sheet steel, to be readily bent, stamped, shaped, etc.
