 Ed,

 Did you mention AC application when you contacted them? If approached as
 racing it "might" fly.

 Ed Carver,
 I have no particular request for 363 over 390, I just found the physical
 property sheet for 363 first. I'll be happy with whichever material is
 superior for the purpose.

 For ceramics, you might visit the Aremco site. Their 502 1400 FF
 might make
 an interesting rotor and their less expensive ceramic plates would
 substitute for the cast iron wear plates. The downside of the
 ceramic rotor
 is the lack of heat transfer.

 Good luck with Starmet. Let me know what you find out.

 Dale, I told them I wanted to make rotors, no mention of aircraft.
 Because I was directed to the aerospace division, it might have been
 better to state my purposes as aerocraft. IBC appears to have a
 commercial division. I've got to ask them if I can buy bar stock, or
 ingot, then ask for a certain amount in weight. I might be better of
 to go through a foundry, or machine shop, or an engineer to get what
 we want.


Doug, do you know why less heat transfer would be bad? Is ductility the
biggest drawback with ceramics? I will dig into it for a while. See if I
can find some specs. I tend to look at ceramics like I look at fire
bricks, heavy and brittle. It's like we're heading back to the stone age
with the stuff. I love it though I guess, if it works.

I'm going to find someone to rep for me, some sort of broker, before I
approach Beralcast again. I think I know some guys around here who
understand the supply chain.

Titanium is known to work. And might not be exorbitantly priced. Can be
cast, just gotta sort out the properties side of it.
