Sintering Molybdenum rod, as the raw material, is mainly used in pulling Molybdenum wire and Forging Molybdenum rod. As Molybdenum possesses the feature of melting point, forging Molybdenum rod with high purity, high density and excellent high-temperature proof of creep deformation is widely applied for electrodes, screw, heating element in high-temperature furnace, rabbles in rare earth smelting industry, and heating electrodes in glass industry and support of lamp in the lighting industry,
