Any suggestions on a tool that is fast and will last on roughing milling 5"×5"×5/8 deep A11?

That's going t depend a lot on just what it is you are trying to do, and what you are trying to do it in ...
Here's a good place to start:
Harvey Tool - Coating Chart for Ferrous and Non-Ferrous Materials!
Iscar makes some good 12 flute half inch endmills. Theyre better for 6Al4V though. I know M.A. Ford makes some good 7 flute half inch endmills as well.
The biggest timesaver IMO is going to be if you can run a dynamic toolpath. You could go the full depth of cut at 5/8" with maybe a stepover percentage of 8 - 12%.
Get some indexable end mills & run it at 18,000 rpm to increase tool life.
