The main reason why certain metals - such as copper or aluminum - are used to make wires is that they are extremely good conductors of electricity. If there were no metal in the wires the electricity would not be conducted by anything.
Another good reason why certain metals are used to make wires is because they are "ductile". That just means they can easily be drawn through a series of smaller and smaller holes - called "dies" - to make wires of various diameters.
Note
To prevent the wires in an electrical cable from touching together - which would make a "short circuit" - or from making contact with other metal surfaces, the wires must be covered in a good insulating material such as a specially prepared plastic or rubber compound.
It is a very good conductor of electricity.
Wires are used as electricity conductors.
Copper is the main metal used for this purpose.
The wires must first be heat resistant. For that the best wires that can be used are wires made up of superconductors.
Metal wires are single strands of flexible material often used to carry electrical currents, telecommunication signals, and hold mechanical loads.
It's partly a convention of terminology; similar items are made from plastic or fabric and they are called "string" or "strands".You may be asking why metals are used for electrical wiring; that's because metals are conductors - that's almost a definition of what a metal is - metallic elements have surplus electrons and conduct electricity.
Copper and aluminum used for electric wires
Copper Metal is used because it is good conductor of electricity
copper as it is a good conductor of electricity :)
Solder is a low melt metal that is conductive of electricity, ideal for forming joints in copper wires, and other electrical devices, etc.
Copper. Because 1, it is A GOOD CONDUCTOR OF ELECTRICITY, AND 2, IT IS A MALLEABLE (BENDS EASILY) METAL.
Wires are used as electricity conductors.
Metal is a very good conductor of electricity. Rubber doesn't conduct electricity.
The metal wires expand in the heat - making them sag.
Pipes, wires.

Household electric wires are covered with plastic or other materials as insulation to prevent short circuits and fires, and to prevent electric shocks.
Copper has been used lately in wires and cables like coaxial and electric wires.
