Explanation

Ductility is the quality of being pliable and flexible, like a piece of metal that can be bent into a thin wire. Metals like silver, lead, and copper have ductility — a metalsmith can bend, hammer, and even stretch these materials without breaking or shattering them. Things like Silly Putty and Play-Doh also have ductility, but your ceramic mug and plastic sunglasses don't. Ductility and the adjective ductile are rooted in the Latin ductilis, "able to be led or drawn."
