I would also of course prefer to not wreck my blade Best to buy a
new one if needed and have 2 than buy a new one to replace the ruined
one.


The 10-14 should be fine, you want a coarser blade because aluminum needs
a lot of gullet for chip evacuation. I cut tons of this type of
extrusion, normally on a miter saw. The hacksaw blades I use for it when
I do have to cut a piece by hand is a 14 tpi.

better idiots.
