Question

Why alluminium is now a days replacing copper for use in electrical cables?

Answer 1

Although silver is the best conductor of electricity, high prices of the metal limits its use. Thus, the most used conductors are aluminium cables and copper cables. Copper has a higher conductivity than aluminium. It is more flexible, has a higher tensile strength and can be easily soldered.
