Jack,
You can of course use any insert at all in aluminum, just be aware that TiN-coated inserts like those shown do tend to get aluminum stuck to the coating. Better uncoated if you can get them.
I wish Mesa would use a common TCGT/TCMT 32.5x size insert! Those TCGB 321 inserts are rather scarce, as the thickness of 1/8" isn't nearly as popular as the 5/32" of a TCGT/TCMT 32.5x size. You can find cheap ones in a few places. Circle Machine (now a part of Kennametal's Widia group) used those in their boring bars.
Good luck!
