I would imagine that you could make a carbon print on aluminum.  I have
also wanted to try anodizing a plate and sensitizing the oxide layer.  A
company called Metalphoto does this commercially, but I've wondered about
using some of the alt-processes.  I have tried anodizing small pieces of
aluminum, that part is pretty easy.
