Non-electrical conductive material for extreme P&T

  1. Dec 20, 2016 #1

    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.

    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 ?
