Copper has very high electrical conductivity, low resistance, good tensile strength and ductility, and is normally not brittle. Other materials with higher conductivity are either too expensive (like gold) or too brittle to be good candidates for wire.

Silver is used as a low resistance conductive material. Contactors and relays contact points are made of copper and are silver plated to obtain the lowest resistance between the moving contact faces.
The two main types of electrical wire are made from copper and aluminium. The copper wires are used mostly in installations up to 3/0. The aluminium wires are used mostly on service entrances and feeders that need conductors above 3/0. This keeps the costs down when larger size conductors are needed.

Usually, you use ETP (electrical grade) copper, which is at least 99.9% pure. It could be different for special applications.
No, copper is commonly used to make wire.

Not a mineral but a metal- copper.
I think copper is cheaper.
Yes. It is used to make wires and cords for commersial uses such as telephone wires etc and is used for other things to.
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.
Copper has been used lately in wires and cables like coaxial and electric wires.
Image result for What is the mineral copper often used to make electrical wires? Because of its superior conductivity, annealed copper became the international standard to which all other electrical conductors are compared. The main grade of copper used for electrical applications is electrolytic-tough pitch (ETP) copper .
Copper is used to make electrical wire because it is ductile and is very conductive. The ease with which copper can be worked and drawn ("pulled" or "stretched") into wire (because of its ductility) makes it a great mechanical choice for wire. And copper is highly conductive, that is, it has a low resistance to electric current flow. These two properties make copper an excellent choice to make electrical wire.
