Wire comparison

For the same temperature and intensity

For the same conductance

Aluminium diameter= Copper diameter x 1,19

Aluminium diameter= Copper diameter x 1,27

Aluminium section = Copper section x 1,42

Aluminium section = Copper section x 1,63

Aluminium weight = Copper weight x 0,4

Aluminium weight = Copper weight x 0,5
