    I am looking for a cheap but strong material with very low heat conductivity. Any idea? This materials would be able to withstand explosion but with very low heat conductivity.

    Might not be strong enough though.
    Edit: it's the only heat resistant metal I know off the top of my head.

    The usual approach to this problem is to use your strong material (carbon steel for example) as a shell and line it internally with layers of refractory brick or castable or ceramic fiber. The refractory accomplishes the low conductivity requirement and the steel provides the strength.

    I am seeking a material for constructing two of a key firearm (M16, M4, AR family) components.

    1. Gas Block
    2. Bolt Carrier Group

    The ideal materials must be heat resistance, low heat conductivity, high strength and light weight. As you can imagine, these component must be able to withstand crushing explosion (from ignition of cartridges) for a long period of time. I am seeking a more advance composite materials to replace the conventional heavy steel alloy.
