It will affect the voltage drop. The wire size would be the same for both copper wires and aluminum wires. They can handle 40 amps at 140 degrees F. But that figure rises to 55 amps at 194 degrees F. That is the same ampacity that professionals associate with a 6-gauge wire. Most professionals would discourage you from pursuing such experimentation in the first place. Wire size is important because it ensures the right electrical flow. Based on Table 310-16 of the NEC, a 6 AWG copper wire for the hot and neutral connections and a ground wire size of 8 AWG will do. The appliance in this case is a home installation of an electric car charging station. The length matters. The breaker should also be from a reliable manufacturer with some proof of testing available. For example, if your voltage drop is 30%, it will be 0.3 in the decimal figure. To add a bit: if you are making a dedicated circuit for something like an EV charger (L2 EVSE) your best bet is to look at the documentation from the manufacturer. If the circuit is 100 amp or less you have to size the conductors based on the 60-degree celsius column unless the breaker and the equipment terminations are rated for 75 or 90 degrees. Speaking of the 6-gauge wire, it can handle a whopping 75 amps at 194 degrees F. Keep in mind that a 4-gauge wire handles 70 amps at the standard 140 degrees F.
