What is ductility of a metal? Does temperature have any effect on a metal's ductility?

Question

Accepted Answer

Ductility is the ability of a metal to deform under tensile stress. Temperature affects ductility.

Ductility is the measure of a metal's ability to stretch without breaking.
Metals with high ductility can be drawn into wires or hammered into thin sheets.
Temperature affects ductility, as heating a metal can increase its ductility while cooling it can decrease it.
For example, copper is highly ductile and can be easily drawn into wires, while brittle metals like cast iron have low ductility.
At high temperatures, metals like aluminum become more ductile and can be easily shaped.
However, at low temperatures, metals like steel become less ductile and can become brittle and prone to cracking.
