1. plural of ductility; the quality or state of being ductile; the ability of a material to be drawn into thin wires or threads without breaking
Usage: technical/materials science; usually used in plural when referring to multiple instances or measurements

Examples

• The ductilities of different metals vary significantly depending on their composition.
• Engineers test the ductilities of alloys to ensure they can withstand stress without fracturing.
• Copper and gold are prized for their high ductilities, making them ideal for jewelry and wiring.
• The ductilities of these materials were measured using standard tensile tests.
• Comparing the ductilities of steel samples helped identify the best alloy for the bridge project.
