3.       Molybdenum spraying wire: Molybdenum Spraying wire is made of 99.95% pure molybdenum metal. It is used as a thin coating on the surface of automobile components subjected to wear, such as piston rings, gearbox synchromesh parts, selector forks, etc. Molybdenum spraying wire is also sprayed onto machine parts such as bearing for repair purposes.
4.       Molybdenum plate: Molybdenum plate is widely used in the construction of furnace tooling and parts and as a feed stock for the fabrication of parts for the electronics and semiconductor industries. We can supply molybdenum plate as per customers' requests.
5.       Molybdenum sheet: Molybdenum sheet is used for fabrication of sintering boats, high temperature furnace heating elements and heat shields. Surface can be supplied in a shiny, matte, or as-rolled condition; dependent upon thickness and width parameters of molybdenum sheet. Molybdenum flat products are rolled and annealed to provide the optimum condition for the desired end use.
6.       Molybdenum electrode: Our glass molybdenum electrodes are formed by isostatic pressing, forging to various of types after sintering with medium frequency furnace and then turning, rolling, planning and milling. We can also offer different kinds of molybdenum electrodes as your requirements. We have produced this kind of molybdenum electrodes for decades, and spare no effort to the improvement of the electrodes' performance.
7.       molybdenum rod: Divided forging molybdenum rod  and polished molybdenum rod; forging molybdenum rod surface is allowed to have oxidize film and slight forging hammer mark; polished molybdenum rod surface presents metallic luster and has no oxidized phenomenon notably;
8.       Molybdenum fabricated parts: Various specifications and shapes of molybdenum special parts can be produced according to the requests of customers: molybdenum crucible, molybdenum  mandrel, molybdenum rod, molybdenum boat, molybdenum pot, molybdenum tube, molybdenum headpiece, molybdenum  electrode/sheet and molybdenum box.
9.       Molybdenum alloy/TZM: TZM is a solid-solution hardened and particle-strengthened molybdenum based alloy. TZM material has better creep resistance and higher recrystallization temperature. TZM has better high-temperature strength and better welding properties. TZM can be used to make components for HIP, sintering and heat treatment furnaces, and boats for annealing and sintering processes (temperatures up to 1400 'C). TZM can be used for rotating anodes for medical diagnostics and forming tools such as hot runner nozzles for plastic injection moulding. TZM can be used to make moulds for light-alloy casting and billets for the isothermal forging
 
Tungsten Carbide products: Tungsten carbide is a ceramic material composed of approximately a 1:1 ratio of tungsten and carbon atoms. For practical applications it is alloyed with >6% of a softer metal, usually cobalt. The primary attraction of tungsten carbide is its high strength and low ductility at high temperatures. Other important properties include thermal and electrical conductivity.
