Max current in copper and aluminum wire
Maximum currents in aluminum and copper wire are indicated in the figure below.
Example - Maximum Current in a 6 mm2 Aluminum Wire
A 6 mm2 aluminum wire is somewhere between AWG #9 and #10. To be on the safe side we use AWG #10 in the figure above and estimates the maximum current in a 6 mm2 aluminum wire to be approximately 30 amps.
