Wire for 50A 220V Service - 110' run
I have on hand about 30' of #2 aluminum wire and about 100' of #6 aluminum wire. The run from the breaker to the outlet will be about 120'. Can I run about 30' or so of #2, then continue with #6 to ...

I guess you could, but I would not use aluminum wire at all. #6 aluminum wire is too small I think for 50 amps.:E
Second. #6 copper might be enough but for a 100 foot run, If you are going to be getting close to 50 amps, consider #4,, let me look up some numbers. 36 Copper has about .04 Ohms per 100 foot. (.08 when you run it back) so at 50 amps that's 4 volt drop in the loop.
#6 Aluminum is .. Far Lossier.. (Frankly I did not find a chart for Aluminum wire) plus you need special connectors on each end to make sure it does not get much worse very fase.. I'd not use Aluminum wire.
