    • Because they are good conductors of electricity, the best one is Silver but is too expensive to use.
    • Both 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
      gold.
    • Aluminium is a much lighter metal than copper - about 1/3 of the density and has better corrosion resistance.
    • Copper 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
