Tungsten and molybdenum members
Tungsten wires are used for filaments by making the best use of their high heat resistance and molybdenum members are used for equipment and vapor deposition trays in the process of vapor deposition of reflective coating.
Molybdenum rods are used as glass melting electrodes by making the best use of their high heat resistance and high electric resistance and tungsten plates are used for fixtures by making the best use of their high specific gravity and high heat resistance in the process of manufacturing glass.
