You'd have to glue the aluminum on, which I wouldn't personally trust. I've used both brass and stainless, depending on what material the shaft collar is made of, and solder to suit. Stainless is of course preferred, but requires a much higher temp to get the silver solder to flow (and silver solder ain't cheap!)
