As suggested long ago, a carbide tipped saw blade cuts neatly through
aluminum. But the ~40 teeth stock blade on my miter saw throws aluminum
chips everywhere. I've tried some modifications to catch the aluminum
chips but none work very well. As mentioned, I tried using a DeWalt
cutoff wheel but apparently that doesn't work for cutting aluminum.

Will a finer tooth (more teeth) carbide tipped blade tend to throw the
chips backwards the way they're supposed to go?

Other options for neatly cutting aluminum with a 10 inch miter saw?

Thanks.
The finer the teeth the better. Makes smaller chips and not as much
heat. The smaller chips don't seem to fly as far.
