      Note: after rolling processing over 60% of the deformation, the density of molybdenum sheet is basically close to the theoretical density of molybdenum. Therefore, it has high strength, uniform internal structure and excellent high temperature creep resistance, which is widely used in the production of the back screen and cover plate in the production of the sapphire crystal growth furnace, the reflection screen, the tropics, the connector, the splash of the plasma coating in the vacuum furnace. Shooting target, resisting high temperature boat and other products.

      Note: sintered molybdenum bar is mainly applied to the raw material of molybdenum wire and molybdenum bar. Because of the high melting point characteristic of molybdenum metal itself, the forging molybdenum rod with high purity, high density and excellent resistance to high temperature creep is widely used in the electrode, screw, heating element, connector, the stirring rod used in the rare earth smelting industry, the heating electrode used in the glass industry and the light bulb bracket used in the electric light source industry.
