Ductility:

Did you know? Ductility is the property of metals that allows them to be drawn into wires. This property is due to the ability of metal atoms to slide past each other when a force is applied. Some examples of highly ductile metals are gold, silver, and copper. Fun fact: Gold is so ductile that a single ounce of it can be stretched into a wire that is 50 miles long!
