A blacksmith hammers a piece of ductile copper into a thin sheet.

Definition

1. Adjective:
   • Capable of being shaped or bent: Describes a material, especially a metal, that can undergo significant plastic deformation without breaking, allowing it to be stretched into wire or hammered into thin sheets.
   • Easily influenced or led: Describes a person or their character as being easily persuaded, manageable, or tractable.

Usage and Examples

• Describing a physical property (of a material):
  • Copper is a highly ductile metal, making it ideal for electrical wiring.
  • The ductile nature of gold allows artisans to craft intricate jewelry.
• Describing a personal characteristic (of a person):
  • He was too ductile in his youth, easily swayed by stronger personalities.
  • A good teacher can be firm without expecting students to be merely ductile.

Advanced Usage and Nuances

• In materials science and engineering, ductile is a precise technical term contrasted with "brittle." A ductile material will deform before it fractures.
  • The bridge was designed with ductile steel components to absorb seismic energy.
• When describing people, the term can carry a neutral or slightly negative connotation, implying a lack of firmness or resolve.
  • Her ductile disposition made her popular but also vulnerable to manipulation.

Variants and Related Words

  • The ductility of the alloy was tested under extreme pressure.
• Ductileness (n): A less common synonym for ductility.

Synonyms

• Malleable: Capable of being shaped by hammering or pressure. (Often used interchangeably with for metals, though specifically implies shaping by hammering, while implies drawing out into wire.)
• Pliable: Easily bent, flexible; also easily influenced.
• Tractable: Easily managed or controlled.
• Pliant: Flexible, bending readily; yielding readily to influence.

• Obdurate: Stubbornly refusing to change one's opinion or course of action.
• Intractable: Hard to control or deal with.
