    MHC alloy is the upgraded TZM alloy product, with superior performance and strength compared to TZM alloy. The new MHC alloy developed by AEM, with oxygen content less than 50ppm, can substitute TZM ally to achieve better efficacy.

    Advantages of MHC Alloy

    Dimensional stability 
    Optimum non-deformability
    High thermal stability
    No cold brittleness
    Good hot ductility 
    Very high crystallization temperatures
