First of all, we must know the properties and applications of molybdenum foil and molybdenum processed parts: in the processing industry, molybdenum is widely used. The mold used at high temperature is subject to fatigue and cracks due to heat and mechanical alternating stress. However, the use of molybdenum or molybdenum-based alloys with small thermal expansion coefficients, strong thermal conductivity and good high temperature strength can greatly extend the life of the mold. When die-casting delicate parts such as watch cases, the life can reach 5000 times, generally 3000 times. Bearings are produced in tungsten plates, molybdenum plates, tungsten rods, molybdenum rods, tungsten tubes, molybdenum tubes, and tungsten crucibles. The bearing steel mold life is increased by 15 times.

When isothermally forging difficult-to-deform superalloys, molybdenum alloy molds can be used at 1200 ° C. Because of its high hardness and high resistance to cold and hot fatigue, molybdenum-based alloys are often used as heads and molds on seamless pipe perforators, and their life spans are hundreds of times longer than that of 3Cr2W8V mold steel. Molybdenum flakes can be divided into light molybdenum foils (PCC) and molybdenum foils (GCC). The characteristics of molybdenum foil can be manually adjusted color, particle size, surface characteristics, dispersion, rheology, thixotropy, and crystal form, etc., and the molybdenum foil has high chemical purity, strong chemical inertness, and good thermal stability, below 400 degrees Does not break down. In addition, molybdenum tablets also have the advantages of low oil absorption, low hardness, small wear value, non-toxic, odorless, odorless, and good dispersibility.

There are several technical points for molybdenum foil:

1. The key to producing high-quality molybdenum foil lies in grasping the quality of raw materials, standardizing operating procedures, and adopting reasonable production processes.

2. The key to improving the surface quality of molybdenum foil is to control the production quality of the surface grinding process and the surface finish of the upper and lower surfaces, and then choose an advanced double-sided four-way grinding machine to make the surface quality accuracy of bright molybdenum sheet products reach the world advanced Level.

In the field of chemical industry, firstly, molybdenum foil can be used as resistance evaporation plating. The common resistance heating evaporation method is to place the evaporation material in a resistance heating device, and provide the evaporation heat to the material to be deposited by resistance heating in the circuit. Vaporization.

In this method, the commonly used support heating materials are refractory metals tungsten, rhenium, and molybdenum. The words metal has the characteristics of high melting point and low vapor pressure. The supporting heating material generally adopts a filament shape or a foil shape. The resistance evaporation source is used to evaporate low melting materials, such as gold, silver, zinc sulfide, magnesium fluoride, chromium trioxide, and the like. The resistance evaporation source is generally made of tungsten, molybdenum, and tantalum. Secondly, it is used in the building and automotive glass industries: GW can provide sputtering target materials for various functional layers for heat-reflective glass and low-e glass (LOW-E) for the building and automotive glass industries. It is suitable for VON ARDENNE, LEYBOLD And other conventional coating systems, specifications can be provided according to customer needs. Target materials include: niobium (Nb), titanium (Ti), tin (Sn), silicon (Si), chromium (Cr), zinc (Zn), aluminum (Al), silicon aluminum (SiAl), zinc aluminum (ZnAl) , Zinc tin (ZnSn), zinc aluminum oxide (AZO).
