Molybdenum is used more widely in the processing industry. Thermal fatigue and mechanical alternating stress at high temperatures cause fatigue cracks. molybdenum-based alloys have small coefficient of thermal expansion, high thermal conductivity and high temperature strength，which can prolong the service life of the die greatly. The service life of the fine parts such as watch case made by G.K.N Co. of UK can reach 5000 times, generally 3000 times. The service life of tungsten plate, molybdenum plate, tungsten rod, molybdenum rod, tungsten tube, tube, tungsten crucible and molybdenum crucible mold made of molybdenum alloy is 15 times longer than that of high speed steel and bearing steel. it die can be used at 1200 degree temperature when isothermal forging is difficult to deform. Because of its high hardness and high cold and hot fatigue strength, molybdenum-based alloy is often used as plug and die in seamless pipe piercing machine. Its life is several hundred times longer than that of 3Cr2W8V die steel.

   Molybdenum sheets are divided into two kinds: light molybdenum sheet (PCC) and molybdenum sheet (GCC). The characteristics of fomer are that they can be manually controlled in color, particle size, surface properties, dispersion, rheology, thixotropy and crystal form. Moreover, molybdenum sheets have high chemical purity, strong chemical inertia and good thermal stability, and can not be decomposed below 400 degrees Celsius. In addition, it also has the advantages of low oil absorption rate, low hardness, low wear value, non-toxic, odorless, tasteless, and good dispersion.
