I agree I have not seen NM aluminum wire since the days of leisure suits but if someone made it in NM-b, you could use it.
The strange thing is, a few years ago, there was a guy from Alcan running a road show telling inspectors what wonderful stuff aluminum wire was, explaining the AA alloy and such.
I thought at the time that they might be trying to rehabilitate the product in a climate of nose bleed copper prices.
I suppose the AFCI would cut into the chances of using fuses but we do have the "device" AFCI don't we? I am sure I saw it in the code somewhere
