The cost factor. Other than that it is an excellent conductor.
It is expensive.
Mainly copper is used for household wiring but it may vary.
For most applications ... where the wire has no function other than to join the components that accomplish the purpose of the circuit ... the best metal to use for wiring would be the one with the smallest resistivity. That would be silver. A big part of the reason that we usually settle for copper is because it is only second best as a conductor and is a lot less expensive than silver.
aluminum
Answer for USA, Canada and countries using similar 60Hz household electrical servicesBlack insulated wire is used for a "Hot" (or "Live") wire. Answer for European and other countries using similar 50Hz household electrical services In old wiring, as was used for household electrical circuits installed in the UK prior to 2006, the "Neutral" would have been a black insulated wire. Black insulated wiring is not used for that purpose today. For more information see the answers to the Related Questions shown below.
Is there such a thing? old wiring is usually copper and the scrap value is quite high.
No. Household wiring requires household wiring.

Common household products containing silver are mirrors, jewelry, coins and flatware, and it is used as a conductor in electrical work. It is also found in some antibacterial products and antibiotic medicines, as well as silver-cadmium batteries

For wiring, we only use copper and silver. The most common conductor is copper. Almost all wires use copper as a conductor.
That depends if it is automotive or household wiring. On a car a black wire is almost always ground. On house wiring black is the supply (hot) wire.That depends if it is automotive or household wiring. On a car a black wire is almost always ground. On house wiring black is the supply (hot) wire.

Silver is, then copper, then gold, and then aluminum. Copper is used for wiring because it is cheaper than silver. Aluminum is not used very much anymore because it can be dangerous when installed improperly.
The answer is copper.No, the answer is not always copper, it will depend on the purposes for which the wires are to be used!Yes, copper is used a lot for electrical wiring but other metals are also used, such as tungsten for incandescent light bulb filaments.Some other examples are: galvanised iron or steel wire is used for fences around gardens, etc. and if wires are used to make jewelry, they are often made of silver, gold or platinum.Another answerDepends on the purpose:for electric household wiring copper is used.for ultra high speed capacity internet communication wiring: glass fibre Comment: Glass fiber is not made of metal, it is made of glass!
