You don't want to grind aluminum as doing so could cause the wheel to explode. If you do grind aluminum, use lots of cutting oil! As a journeyman prototype machinist, that is one of the first things learned in the trade. Brass and other non-ferrous metals are similar but not so bad as aluminum as it gums up the pores in the wheel.
