If you feel you won't shuck teeth from the blades, a bi-metal is very good,
but I don't use them. I've stayed with carbon steel blades for a couple
reasons. One, I usually damages a blade well before wearing it out, or (2)
it breaks from fatigue before you have the miles from it.

I have been using Morse bi-metal blades almost since I got my saw three
or four years ago. I have been cutting everything from EMT and .035
wall 2" Al irrigation pipe to 4130 1/8" plate and (Harold's favourite
material, NOT) OCS with a 14 tpi plade. Most recent cut was a piece of
5" diameter 6061-T6. I had to remove about 30 thou facing cut to get
that last one square. I put some light up pressure by hand on the end
of the saw arm when cutting thin wall stuff. I once damaged a toth a
couple years ago.

When I got the saw it had a carbon steel blade. It was toast. I had
been advised to use carbon steel blades since they were much cheaper. I
bought two. Big mistake. They last about a week each. Princess Auto
had a sale on the Morse bi-metal. Bought six. Still have 2 unused
hanging on the wall and one on the saw. One, as I said, I damaged. The
others two were plain wore out.

Regardless of
your choice, though, I think that the blade stock in question might be .025"

That is correct. 0.025" thick.
