Electrical wiring needs to be made of two main materials: a good conductor of electricity, usually copper, and - to prevent the wires inside a cable from connecting to one another - a very good insulator, usually pvc (poly-vinyl-chloride) or special rubber.
Cables used for special scientific or military uses may use silver or gold for their wires even though they are very expensive compared to copper.
Aluminum is a cheaper alternative to copper, silver or gold. Aluminum is a much lighter and cheaper material to use as a conductor but you must give up some amperage versus a cable that is the same size, but made from copper, because aluminum is not such a good conductor.
copper is used for conductors, plastics are used for insulation, steel is used for conduit
