What's the difference between ductile and elastic?

Ductile

  • (a.) Capable of being elongated or drawn out, as into wire or threads.

Elastic


Definition:

  • (a.) Springing back; having a power or inherent property of returning to the form from which a substance is bent, drawn, pressed, or twisted; springy; having the power of rebounding; as, a bow is elastic; the air is elastic; India rubber is elastic.
  • (a.) Able to return quickly to a former state or condition, after being depressed or overtaxed; having power to recover easily from shocks and trials; as, elastic spirits; an elastic constitution.
  • (n.) An elastic woven fabric, as a belt, braces or suspenders, etc., made in part of India rubber.
