Molybdenum is the most widely used in the process industry. The mold used at high temperatures is subjected to heat and mechanical alternating stress, which leads to cracks in the material's fatigue. However, the use of molybdenum or molybdenum-based alloys with a small thermal expansion coefficient, strong thermal conductivity, and good high-temperature strength can greatly extend the life of the mold. British G.K.N company die-casts watch cases and other delicate parts, with a lifespan of up to 5,000 times, generally 3,000 times. In the production of bearings, tungsten plates, tungsten crucibles, and molybdenum crucibles use molybdenum alloy molds, which are 15 times longer than the original high-speed steel and bearing steel molds.

When isothermally forging high-temperature alloys that are difficult to deform, molybdenum alloy dies can be used at 1200°C. Due to the relatively high hardness of molybdenum-based alloys and high resistance to cold and heat fatigue, they are often used as plugs and molds on seamless pipe piercing machines in industrial processing, and their service life is much longer than that of 3Cr2W8V die steel. There are two types of molybdenum sheets produced industrially: lightweight molybdenum sheets (PCC) and molybdenum sheets (GCC).
The characteristics of molybdenum flakes are that the color, particle size, surface characteristics, dispersion, rheology, thixotropy, and crystal form can be manually adjusted, and molybdenum flakes have high chemical purity, strong chemical inertness, and good thermal stability. will break down. In addition, the molybdenum sheet produced by Baoji Yusheng Metal Technology Co., Ltd. also has the advantages of low oil absorption, low hardness, low wear value, non-toxic, odorless, tasteless, and good dispersibility.
