The whole point of an ATB is its strength. The zero-ish hook-angle
adds to that. If I need to cut aluminium or solid surface, that would
be the blade I'd chose.
I have seen 6" blades like that on automated equipment. Different
bores though.

Non-ferrous metal and plastic. Thin stuff.

I used to see a few 6" saws on construction sites in California...
As I remember, they were smaller, lighter and higher RPM than a standard
circular saw..
Not much depth of cut, obviously..

The saws for cutting printers lead type are about like that.

It's always possible that it's a metalworking slitting or slotting
saw, made for use on a milling machine. If it is, the arbor hole is
likely to be 7/8", 1" or 1-1/4", with a notch for a key. The 6"
diameter would be a common size.
The milling cutters would usually be either square ooth or alternate
face bevel though, not typically alternate top bevel.
