Here's a 14-50 that specifically says it'll work with aluminum conductors:

Other than the HPWC install guide, which is very specific and says CU only(when connecting to the HPWC!), there's nothing to my knowledge saying you can't use aluminum in an EVSE circuit. If you have a reference, please share it.

Side note: even if aluminum is allowed to be used in a circuit, I'll never use it myself by choice.

I was wondering the exact same thing. I've actually been tempted to reinstall the Leviton to test again.
Unfortunatly I completely forgot about testing the tightness as I was on a mission to quickly replace the receptacle. I had the family awaiting the power to be restored 🤣

I think I'll try and find time to give it a try again with the Leviton this week and report back.
I would not use Leviton receptacle for charging the EV since it is rating for residential not industrial. Hubbell/Bryant is the one to use.. Just make sure you torque the screw on each wire properly.

Leviton manufactures different model 14-50 receptacles that are made to sell at different prices depending on the application. The basic Leviton 14-50R (model 279-S00) is fit for purpose if your application is for providing 240V/50A power for an electric range or wall oven. You should not rely on the Leviton 14-50R model 279-S00 for EV charging as there are many cases of this receptacle overheating when charging an EV. If you are installing the 240V/50A circuit with a receptacle for EV charging then use one of the recommended 14-50R or 6-50R from Hubbell (14-50R: 9450a), Bryant (14-50R: 9450fr) or Cooper (14-50R: 5754n)
