Because molybdenum plates have excellent high temperature resistance, corrosion resistance, high strength, high hardness and other properties, they are widely used in national defense, aerospace, glass fiber and other industries.
Molybdenum plate has very good thermal conductivity and does not react much with thermal expansion and contraction during use. Its good electrical conductivity has become an important material in the electronic and power equipment manufacturing industry. Of course, it is also used very well in some other industries. . Because molybdenum plates can withstand high temperatures of 2,900 degrees in vacuum, they are currently the most widely used thermal conductive material in the spacecraft industry.

The main applications of molybdenum plates are as follows:
1. Molybdenum plates serve as heating elements, heat shields and high-temperature structural parts of high-temperature furnaces;
2. Boat blood for molybdenum plate evaporation;
3. Molybdenum plates are used as automobile heat sinks;
4. Molybdenum plates are used as molybdenum discs in the rectifier industry;
5. Molybdenum plates are used as molybdenum electrodes in the glass and glass fiber industries;
6. Molybdenum plates are used as components of electric light sources, electric vacuum and power semiconductor devices;
As a new product of molybdenum plate, molybdenum sputtering target is also the product with the highest market demand and fastest growing market. It is mainly used in the information industry, photovoltaic industry and LCD display industry.
Molybdenum plates are widely used in the construction of molds and parts furnaces, high-purity molybdenum plates for electron beam sputtering targets, ion implanter parts, and semiconductor heat dissipation components. The purity of the slab is required to be greater than 99.99%, the density is greater than 9.8g/cm3, and the grain size is 2000~3000 pieces/mm2, smooth surface, no cracks, no unevenness.
In short, molybdenum plates are mainly used in military, electronics, glass, aerospace and other industries.
Product process
First, molybdenum slab (raw material) for the corresponding inspection, in the hot rolling treatment, leveling, and annealing after the good.
The next line of alkali washing, in the inspection, is to determine whether there is a problem, no problem after rolling.
The next step is vacuum annealing, then inspection, no problem after cold rolling, in further leveling, shear, vacuum annealing, in the second inspection, no problem after packaging.
