Default Cutting non ferrous metals with a table saw

I have some door kick panels, some brass and a couple of Al ones. I
have used these before to make enclosures but in the past I always cut
them with a reciprocating saw then did a lot of filing to get the
edges straight and pretty. I was wondering if I could cut these using
my table saw. The motor is sealed so I don't have to worry about
getting metal shavings in it. Anyone here ever done this before. If so
what kind of blade did you use? Were there any special techniques you
applied?


Fine-toothed circular saw blade made for cutting metal works wonders
on not just aluminum and brass but also many hard plastics.

You will probably not find the optimal blade at your local home depot
or hardware store. Check out mcmaster.com

If you can clamp the material or build a custom fence to hold down
thin material you will greatly reduce the vibration and noise.

Ear and eye protection is a must.

Believe it or not, I have seen aluminum machining done with a 2 or
2.25 HP electric router on long (20, 30 foot) bars for cutting slots
etc.
