Table saws and cut-off or miter saws with large carbide tipped
coarse tooth blades designed for soft metals work perfectly.

Depends on how careless the operator is. The first thing that happens
with solid disc cut-off wheels or fine tooth cutting tools is the
clog up or coat themselves with aluminum. I suppose if you continued
to force the wheel against the work with a lot of pressure it would
shatter, but normally they just won't cut.

They always tell people in the instructions what the blades are good
for. I haven't seen any suggestions to use a cutoff wheel, just
carbide tipped blades.
Aluminum loads up anything except very coarse tools. Working with
soft aluminum, we use a thin coating of transmission fluid on
cutting, milling, drilling, and tapping tools. While messy, the tools
cut much faster and last much longer. Even hacksaws.73, Tom W8JI
