# Copper and Aluminum Wire - Max Amps vs. Gauge

Maximum current in aluminum and copper wire with ambient temperature 86oF (30oC):

#### Example - Maximum Current in 6 mm2 Aluminum Wire

6 mm2 aluminum wire is somewhere between AWG #9 and #10.  To be on the safe side we use AWG #10 (the smallest one) in the figure above and estimates the maximum current to be approximately 30 amps.
