As far as I know it could be used, like you say it is conductive so
the process will occur, it doesn't rust either so would seem OK at
first glance. One thing that might be an issue is the flushing
pressures, they are higher than for EDM I think (not sure) but it
would depend very much on what is being machined.

Of course there is no reason why brass or aluminium could not be used
either, both of which are easier to machine than copper. As far as I
am aware the electrode material has no bearing on the process, some
materials may take some plating more than others I'm not sure.
General corrosion is another issue.
