Molybdenum carbide has a high melting point and hardness, good thermal stability and mechanical stability, and excellent corrosion resistance and other characteristics. Molybdenum is a silvery white refractory metal, a melting point of 2615 ℃, density of 10.2 g / cm 3, the expansion coefficient is small, a special tube is almost the same coefficient of expansion of the glass. Molybdenum stable at room temperature is higher than 600 ℃, rapidly oxidized.

Can you explain the specific carbide is used in what areas will be used? Liu
According to Voice of the economy "Transaction live" reports, analyst at Huatai Nonferrous Metal Industry Liu guest "trading live" as we interpret the investment value of tungsten ore, tungsten ore Liu considered the best future growth in demand or in the carbide fields. Moderator: Can you explain the specific carbide is used in what areas will be used? Liu: Hard alloy system has three major application areas, the first is industrial processing tool, and the second is used to open the mine oilfield drilling, and the third is commonly used in industrial wear parts. Moderator: Can you explain the specific carbide is used in what areas will be used? Liu: Hard alloy system has three major application areas, the first is industrial processing tool, and the second is used to open the mine oilfield drilling, and the third is commonly used in industrial wear parts. Moderator: Carbide or in addition to this demand than other areas in the downstream tungsten ore demand growth there is a large space which is not, in addition to carbide outside? Liu: Other areas include them in special steel as the tungsten additive; Also in some chemical categories were also put tungsten as an additive or catalyst, in addition to doing the other is tungsten carbide, also made of alloy and other metals used in many business processing materials; additional lighting in the area is used for tungsten wire, tungsten materials, future growth in demand for the best or in the field of carbide, as China gradually to the Molybdenum tube tool is present stage of high-end forward, basically in other areas and national economic growth will keep pace steady growth. Moderator: At present, China's tungsten industry chain development is kind of how it? Liu: The so-called high-end forward is that in the end the finished tool above, such as Israel on the machine, the original are used in traditional ordinary machining tools, the current relatively high-end digital processing machine tool consumption among the proportion has increased significantly, the traditional machine tool may gradually decline, the future may be more high-end coated tool bit conversion tool is to use hard tungsten production, consumers will have certainly a very significant increase in the current number of major tool manufacturers are also on the new production line is mainly invested in coated tool above.
