The hardness part of this statement does not match my experience. As I understand it, its advantages are flatness and stability when machined. I'm pretty sure the stuff I have is real mic6, not one of the many copies, and it isn't particularly hard. Although I generally have to drop something on it to cause a problem. The stability part would be good for an alignment table. I think it would work fine for what you are proposing to use it for.
