2. Metals are Ductile.
This means that metals can be drawn (or stretched) into thin wires. All the metals are not equally ductile. Some are more ductile than the others. Gold and silver are among the best ductile metals. For example, just 100 milligrams of a highly ductile metal like silver can be drawn into a thin wire about 200 metres long. Copper and aluminium metals are also very ductile and can be drawn into thin wires which are used in electrical wiring. Thus, ductility is another important characteristic property of metals. From the above discussion we conclude that metals are malleable and ductile. It is due to the properties of malleability and ductility that metals can be given different shapes to make various articles.
