This is what I found Friday morning at my first call of the day for an " intermittent power problem"..
Yes that is aluminum wire in those " backstab" connections, the ONLY connections on that receptacle! If you look at the front fiew of the receptacle you can see it is even stamped "CU-AL"! ( Noticed that after scraping about 10 layers of paint off the thing).
You can sort of see near the plate mounting screw hole, where the innards of the device got warm enough to actually turn the plastic brown. Even the side view shows a little browning of the plastic right near where the little tab to split the device is located..
