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.
I think copper is cheaper.
Copper has been used lately in wires and cables like coaxial and electric wires.
Copper is used for telephone wires because it is the second best conductor of electricity after silver (which is a little pricey).
Wires.

Pipes, wires.
Copper stays where you put it much better than saline water does.
Copper
The most common electrical wires used in residential wiring projects are copper wires. Copper wires are preferred for their conductivity, durability, and safety features. They are typically used for both hot and neutral wires in electrical circuits.
copper is a very good electrical conductor. it's also used in wires because it's very maleable.
Silver is the best conductor but copper is used because silver is too expensive.
Yes it is routinely used for that purpose
