Why copper and aluminium wires are usually used for electricity transmission?

1Because they are good conductors of electricity, the best one is Silver but is too expensive to use.
2Both metals have a low resistance to conductivity. They are extremely
flexible and do not degrade under electrical transmission as do other
metals. They are less expensive than the best conductors, silver and
3Aluminium is a much lighter metal than copper - about 1/3 of the density and has better corrosion resistance.
4Copper is mainly used in low voltage applications.
One advantage of coper over aluminium is that it can be soldered easily which is a big advantage in electronic devices
