(I won't say I'm a machinist), I agree, but brass is still
My reasoning is that any brass you find will be very good
for machining, and adequate for strength. I can't say the
same about any aluminum you find.... imagine the recycled
chewing gum they sell as aluminum stock in the hardware store.
If you really use 6061, and especially T6061, you will have
a working collet when you are done.
The original was a plastic collet with a 6-32 screw molded
into the plastic. So overall strength is not much of an issue.
I don't think it very much matters what you make it out
of... even some plastics would be fine, if you can cut the
threads to size.
The collet doesn't screw into anything. The threads are used
as the collet closer, and are pulled with an ordinary nut.
The collet's tapered cone is inside of the fan's hub.

Chuck, the 6-32 thread won't be any stronger in brass than in aluminum - in fact most likely weaker. Two benefits to brass as I see it are easier machining and less likely to corrode and seize the thread - the likely culprit if aluminum ones are breaking. What material are they screwed into?
