Ductility property

Ductility of metal by which that permits it to be permanently drawn, bent or twisted into various shapes without breaking.

The ductility of the material enables it to draw out into thin wire on the application of the load.

The ductility decreases with the increase of temperature.

It is determined by percentage elongation and percentage reduction in the area of metal.

The types of metal commonly used, because of their high level of ductility, include the following: gold, silver, copper, and steel.

Ductile metals are greatly preferred for aircraft use because of their ease of forming and resistance to failure under shock loads.

The power of changing shape without breaking when the material is subjected to percussion is called malleability, a property closely related to ductility and illustrated by the same class of metals. 
When we can see the same case properties it is necessary to know the difference between them.
