AI Thread Summary
The discussion centers on the search for a non-electrically conductive material that can withstand extreme conditions, specifically with a yield strength of around 1100 MPa at 200°C. Participants clarify that the material does not need to be an insulator but must be stable and electrically non-conductive. Aluminum oxide ceramic is suggested as a potential option, although its flexural strength is lower than desired. There is also a recommendation to consider redesigning the housing to utilize more readily available materials. The conversation highlights the importance of balancing material properties with practical sourcing considerations.

Hello!

I'm building a thing that needs to survive in extreme conditions.
So I'm looking for a non-electrical conductive material that has a yield strength around 1100 MPa at temperature around 200 C.

As long as the material is available on the market, cost will not be a problem.

We really do need to have you very carefully parse this expression for meaning.

Edited. Sorry for my english
 
Is the material "an insulator?" Is it not?

You want it to be electrically nonconductive?

Or, maybe you want it to conduct heat but not conduct electricity?

Sorry for the late reply, it has not to be an insulator. It is more like a housing.

Thanks for the reply. I just want it to be electrically non-conductive. I just need a material that is stable at these temperature.
 
Aluminum oxide ceramic has the compressive strength and temperature resistance you want. It's flexural strength is only around 330 MPa, though.

I think you may want to redesign your housing to use something easier to source.

Why do you need a material that would have to be stronger than most high tensile steels just for a housing ?
