    Just about anything is good enough for a rolling nut if reinforced with a bit of steel, but if i we're using aluminum by itself i wouldn't use a prod that pulls more than 90 pounds.

    I have used aluminum bar stock for roller nuts in the past.  In fact, it's very strong, if you fit a bit of steel allthread rod for a sear.  So much for the good news.
    The bad news is: aluminum is a bitch to cut... very sticky and surprisingly hard to cut and harder to file.  When you get your aluminum nut made, and a steel sear plug inserted in the bottom, you'll discover the stuff oxidizes on the outer surface.  This oxide wears off on the inside of the nut-socket and also gets spread all over the top (table) of the stock... The first few shots you make after it's been sitting a while, will hang up a bit.  After that, it should shoot okay. If you can live with the grey oxide all over the top of your stock, you should be good. 
    Personally I recommend Delrin rod for a roller-nut, or if you have access to a decent lathe, get a piece of moose-horn (base of the horn, where it comes off the head) and turn that down for a nut.  It's what the ancients used.  Geezer.
