I spent some time in a machine shop as well. We used to cut sheets of aluminum (1/4" thick) on a 8" table saw. I don't think the blade was anything unusual, just carbide. Made a hell of a lot of noise. Given options this would not be my first choice, it just never felt quite right.
If I were cutting 1x2 stock as you describe, I would probably stick to a jig saw or band saw with a fine tooth bi-metal blade.
In truth a hacksaw shouldn't take too long.
