What's the difference between ductile and plastic?

Ductile


Definition:

  • (a.) Easily led; tractable; complying; yielding to motives, persuasion, or instruction; as, a ductile people.
  • (a.) Capable of being elongated or drawn out, as into wire or threads.

Example Sentences:

  • (17) The ductility and malleability of pure silver allow for ease of adaptation or alteration as a chairside or operating room procedure.
  • (18) (3) The simulated ceramic firing cycle created a small amount of ductility in SMG-2, but the lowering of the yield stress in Ceramco-0 renders the welds dangerously weak even with improved ductility.

  • (20) The superior ductility of needles made by one manufacturer was related to the specific alloy, stainless steel ASTM 45500, used in their production.

Plastic


Definition:

  • (a.) Having the power to give form or fashion to a mass of matter; as, the plastic hand of the Creator.
  • (a.) Capable of being molded, formed, or modeled, as clay or plaster; -- used also figuratively; as, the plastic mind of a child.
  • (a.) Pertaining or appropriate to, or characteristic of, molding or modeling; produced by, or appearing as if produced by, molding or modeling; -- said of sculpture and the kindred arts, in distinction from painting and the graphic arts.

Example Sentences:

  • (1) The various evocational changes appear to form sets of interconnected systems and this complex network seems to embody some plasticity since it has been possible to suppress experimentally some of the most universal evocational events or alter their temporal order without impairing evocation itself.
  • (2) With the exception of PMMA and PTFE, all plastics leave a very heavy tar- and soot deposit after burning.
  • (3) The consequences of proved hypersensitivity in patients with metal-to-plastic prostheses, either present prior to insertion of the prosthesis or evoked by the implant material, are not known.
