Copper
Copper is used for telephone wires because it is the second best conductor of electricity after silver (which is a little pricey).
Nickel cannot replace copper in copper II sulfate because nickel is higher in the electromotive series than copper.
Mainly copper.
Mainly all telephone wires are made of copper with a plastic coating for insulation. Older form of telephone wire had a paper or pulp insulation over the copper wire. They are also a twisted pair cable.
coaxial cable has a solid copper or copper-clad-steel centre conductor surrounded by a non-conductive dielectric insulating material. The dielectric is surrounded by foil shield/s and/or copper braid/s which form the outer conductor and also shield against electromagnetic interference (EMI). The outer conductor/shield is encased in a PVC jacket.
