The short answer... No.
So now the explanation. As copper and aluminum are two dissimilar 
metals, if you have an electrolyte you will have made a battery.
Aluminum Ox. and water create a real good electrolyte.
So if you don't take the right precautions the galvanic currents 
will reduce your aluminum to a white powder. Not good for support
I would guess.
If you still want to do this invest in some Penetrox B or other
such product. 
I would try to think up a different way of hooking up 
your ground to the tower (a CU to AL lug maybe)
Good luck.
