Copper is always preferred in houses because it conducts electricity better and does not corrode on the surface as easily as aluminium.
But for overhead electric wires, aluminium is preferred because it is much lighter and the pylons don't have to be so massive.
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
