The "metal" in electric wire is called the conductor. Many materials are used to transmit electrical energy, but those most frequently used are copper, copper-covered steel, high strength copper alloys, and aluminum. For more unusual applications, conductors are fabricated from pure nickel (high temperature applications), pure silver, copper-covered aluminum, and a host of metals, metal alloys, and metal combinations. The most common found in everyday wire is copper which is available in stranded or solid configurations.
High strength alloys - Though more expensive than copper-covered steel wires, copper alloy conductors are specified because they permit significant size and/or weight reductions especially important in computer and aerospace applications. They offer high breaking strength and greater flex life with only a small increase in DC resistance.

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.NoteTo 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.
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.

Copper
Even though silver is the best conductor of electricity, it is extremely expensive. Thus silver is not used to make electical wires. Silver is also very soft to be used as electric wires.
Solder is a low melt metal that is conductive of electricity, ideal for forming joints in copper wires, and other electrical devices, etc.
Lead could fall into that category.
Copper is used in wires and water pipes. The properties that make copper suitable for electric wires are:-1. Ductile2. high melting points3. good conductor.The copper used in electric wires has to be purified up to 99.99%, because impurities decreases its rate of conductivity.
Copper and aluminum are good conductors. Other conductors like silver aren't used to make electric wires because copper and aluminum are cheaper but have the same properties.
Wires are used as electricity conductors.
Pipes, wires.
