China tungsten ore great country into powerful imperative tungsten mine
As an important strategic non-renewable resources scarce, big country the United States, Russia and other tungsten has established a strategic reserve.
 
In the defense sector, the most important application is the manufacture of tungsten tungsten alloy. Relevant information, the needs of our military with 11% tungsten tungsten demand, while the US military use of tungsten demand accounted for 20% is reached.
 
Industrial teeth powers scarce strategic resource
 
Tungsten is extremely important as industrial materials, mainly for carbide, tungsten materials, tungsten and tungsten steel chemical. Wherein tungsten carbide is the most important downstream applications. From an international point of view, demand for tungsten carbide industry accounted for 72% of the total consumption of tungsten; the current ratio of around 54%. Over the past few years, the domestic consumption of tungsten carbide industry nearly 11 percent per year growth, coupled with strong domestic demand for metal cutting, the next volume and the proportion of their consumption of tungsten will rise further.
 
In the long run, tungsten is irreplaceable national economy and national defense on the basis of modern materials and strategic resources, manufacturing tungsten carbide has excellent wear resistance, used in the manufacture of cutting tools, cutting tools, drilling tools and wear parts therefore known as "dental industry", widely used in military, aerospace, mechanical processing, metallurgy, oil drilling, mining tools, electronic communications, construction, etc; in addition, is also a key material tungsten lighting, electronics and other industries .
 
Lack of domestic high-end manufacturing capacity
 
From the scale of production and market capacity, China is already the world's largest producer of carbide and consumer. From the point of view of production capacity, China accounted for 38% of global production of carbide production; capacity from the market point of view, China Carbide sales accounted for 26% of total global sales.
 
However, domestic carbide enterprise technology and equipment behind, less R & D investment, the lack of high-end technical personnel, R & D capability is weak, middle and low production of carbide products are still the main, and most just sintered products can not meet the domestic the demand for high-tech manufacturing carbide cutting tools, required a large number of domestic manufacturing enterprises of high-performance, high-precision CNC blade and other high-grade carbide, tungsten products with high added value still has to import from abroad.
 
Tungsten alloy is the most important application of national defense
 
As an important strategic non-renewable resources scarce, big country the United States, Russia and other tungsten has established a strategic reserve.
 
In the defense sector, the most important application is the manufacture of tungsten tungsten alloy. For example, tungsten steel manufacturing modern weapons mainly steel, steel, tungsten content, although only about one percent, but the performance improvement of the steel is extremely significant; Again, the barrel of the gun used in the manufacture of tungsten steel can be effectively overcome its tendency to temper brittleness and improve the strength of steel and hardenability; in addition, the metal tungsten is the highest melting point, and wear-resistant, can withstand high pressure, heat stress is a common element of superalloys, aviation engine with high temperature alloys, rocket nozzles and other key raw materials.
 
Currently, research in missile rail guns are selecting tungsten or tungsten silver copper material to manufacture. In addition, the tungsten-containing materials such as high-speed steel tools, carbide is also widely used in weapons and aerospace equipment manufacturing and processing. Relevant information, in our country, the military needs of 11% tungsten, tungsten demand, while the US military use of tungsten demand accounted for 20% is reached.
