Alcoa Mic-6 looks like a very stable metal at high temperatures.
Are you planning on printing directly onto the aluminum plate?
How flat of a surface do you require?
You could use a lapping plate to get it flatter.
You might be able to get away with adhesive backed wet/dry sand paper.
I have a pair of cast iron lapping blocks for steel, but it's not recommended for aluminum.
For lapping various grades of aluminum metal the Garnet and
Silicon Carbide compounds are recommended.

Alcoa Mic-6
Cast Plate allows high-speed metal removal with little, if any,
of the distortion commonly inherent in long grained wrought, flat-rolled metals.
Flatness tolerance is maintained within .005" on 3/4"- 4" thickness.
Thermal Cycling can be performed up to 800° F under controlled conditions.
