Tungsten and molybdenum play a very important role in our industry
In the atomic energy industry, tungsten and molybdenum are indispensable additive elements and high temperature resistant components of cladding alloys.
Tungsten, molybdenum and its alloys are used in the manufacture of welding electrodes and other structural elements in the electronics industry and electric light source industry.
In mechanical industry and electrical industry, used in the manufacture of various precision instruments in the spring wire, high temperature resistance in the heating body, vacuum spray with spiral coil and boat, etc.
Thermocouple in the thermal industry, using tungsten rhenium thermocouple has ideal high temperature mechanical and thermoelectric properties. It can measure the temperature range of -15.6℃ ~ -3103℃, and high accuracy (error is only 6.6℃), fast response time (1/4 second).
Compounds of tungsten and molybdenum are also widely used in textile, medicine, glass and other industries. In addition, the production of tungsten and molybdenum products for electric vacuum is an important part of tungsten and molybdenum metallurgy.
China's tungsten ore reserves account for more than 50% of the world, and molybdenum reserves are also quite rich. We have made great achievements in tungsten and molybdenum powder metallurgy, but there is still a big gap compared with the developed countries in the world. We should redouble our efforts to make our tungsten and molybdenum products enter the world market in the shortest possible time, so as to catch up with and exceed the world advanced level.
