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 the outlet? Feasible/possible/stupid idea or what?

Thanks.

    I would not run aluminum wire at all let alone spliced but for your distance I'd use #6 solid copper wire. Aluminum has problems with heating up and corrosion.

    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
