    Molybdenum Heating Shields

  • Description:

    As a global leader in serving the high-temperature furnace industry, AEM provides high quality molybdenum heat shielding materials, components and assemblies manufactured to customer specifications. Our sheet material is of the highest quality to ensure the expected performance within your furnace application. We provide sheet in many geometries and materials for our customers to fabricate shielding or we can fabricate to customer specifications. In addition, we are available to partner with our customers to improving heat shielding designs by leveraging our experience and expertise.
    Standard: ASTM B386
    Material: Mo-1, Mo-2, >99.95%
    Density: >10.20g/cc
    Application temperature environment: <1900°C


    As the heat-shield parts in the sapphire growth furnace, the most decisive function of molybdenum reflection shield is to prevent and reflect the heat in the furnace. Heat-shield parts with high-density, exact-measurement, smooth-surface, convenient-assembly and reasonable-design has great significance in improving the crystal-pulling.


    Heat shields can be made any size and configuration. Dimensions and tolerances are according to customer’s drawings. High-quality shield production provides exceptional heat resistance of molybdenum and reliability. Price depends on size, complexity, configuration, and additional requirements specified in the inquiry.
