I have no experience with aluminum dogs, but I would stay away. As Andy mentioned above, the edges are likely to round. Once this begins to happen, you may see another problem occuring: the dog may be forced out of its mating gear. Dog gear interaction needs to be parrallel with the turing shaft. Any lead in our rounding acts like a cam, forcing the dogs apart while under a radial load.
