Best Answer

1 mm2 aluminium wire is not easy to buy but 1 mm2 copper wire is rated at 10 amps. Since the conductivity of aluminium is 7/12 that of copper, 1 mm2 aluminium wire would be rated at 7½ amps max (the same amount of heat is produced per metre by a current of sqrt(7/12) times that for copper).
