Is ductility considered as a physical property or a chemical property

Ductility is a physical property.

A physical property of a material is a property that can be measured or observed without changing the composition of the material.

In this case ductility is a physical property. It is defined as the  property of a material associated with the ability to be drawn or stretched into a wire without breaking. The chemical identity of the material is not affected, that is  it does not change.

Example of ductile materials include gold, silver, copper, erbium, terbium and samarium.

Other examples of physical properties are:

1. Solubility

2. Melting point.

3. Boiling point.

4. Color

5. Density.
