I have made boxes out of brass and aluminum . Brass adds bling but its adds more effort to the machining process . According to the foundries I dealt with brass has less shrinkage than aluminum , but when cast in this shape the opposite was true . The aluminum case shrunk much less and required no internal removal of material to get all the parts in .Big time saver ,also it was much easier to located all the holes . I never had clearance problems using aluminum . Not as pretty but easier to machine and that's my 2 cent's worth
