Tungsten is extremely scarce and irreplaceable strategic resource , but also the national economy and national defense irreplaceable foundation of modern materials and strategic resources , manufacturing tungsten carbide known as "dental industry ," Carbide is widely used in military , areas of aerospace, mechanical processing , metallurgy, oil drilling , mining tools, electronic communications, construction , etc., is the key material tungsten lighting , electronics and other industries. In these applications, has not yet found a direct substitute for tungsten.

Currently, only the world's total proven reserves of tungsten 2.898 million tons , is extremely scarce resources , more than 20 kinds of the world's known tungsten minerals , industrial value only scheelite and wolframite are two, are of high quality wolframite tungsten ore, scheelite are refractory ores . China 's tungsten resources abundant , accounting for nearly 70% of the world 's proven reserves of tungsten mineral resources , ranking first in the world .

2010-2013 , equivalent to the amount of tungsten concentrate production increased year by year , and reached its highest level in 2013 , tungsten concentrate production was 138,000 tons .

Through the analysis of primary tungsten and "Twelfth Five Year Plan" according to the analysis of waste tungsten tungsten industry, we assume that the future of native producers of tungsten in tungsten concentrate production quota increase of 1% per year , the 2017 Chinese tungsten concentrate equivalent to the amount of production will reach 143,600 tons .

Chinese tungsten ore market research report analyzes mentioned in 2014-2017 , has been the domestic and international market demand for tungsten basically showing steady growth in the state . Although the impact of the financial crisis is not over , the European sovereign debt crisis is still spreading and so the constraint of global economic development, but the trend of global economic growth will continue, tungsten demand will continue to grow in 2015 , total global demand may up to 83000t, with an average annual growth rate of 4%.

W-Cu composite material is a high melting point , high conductivity and high density of tungsten and a low coefficient of expansion , high thermal conductivity copper composition , both the advantages of both can , having high thermal conductivity properties such as low expansion coefficient , good high temperature strength and arc erosion resistant properties. As early as in the 1930s , tungsten -copper composite material due to its good compressive strength and resistance to electrical ablation performance, high-voltage electrical switches and other industrial sectors has been widely applied . Into the sixties, tungsten -copper composite material gradually gained in the field of resistance welding electrodes , aerospace and high-temperature parts. Since then, with gradually improved preparation technology , electronic packaging and in the nineties as a heat sink material began in the field of LSI and high-power electronic devices such as access to a wide range of applications . Into the 21st century, tungsten -copper composite material is used as cover material HEAT medicine , materials and target missile nozzle caused concern in the military and high-tech fields .

Now , tungsten -copper composite material due to its good electrical conductivity , thermal conductivity and excellent thermal stability , has become a high-power microwave devices and ultra large scale integrated circuit substrates , embedded blocks , essential key material connections and cooling components , etc. its high thermal conductivity , high thermal stability and good formability near net sizes , can improve the use of power microelectronic devices , is conducive to miniaturization of devices and sophisticated development. Low thermal expansion coefficient and the thermal expansion coefficient of tungsten-copper composite material adjustability , enabling connection to match its semiconductor materials and microelectronic devices with silicon , gallium arsenide and other useful ceramic materials , to avoid thermal fatigue damage caused by thermal stress broaden the tungsten -copper composite material in the field of microelectronics applications.

Tungsten -copper composite material due to its high electrical conductivity, thermal conductivity, excellent arc resistance , anti-friction and thermal stability , have already obtained important applications in rail guns , rockets and missile nozzle throat rudder and other high-temperature gas fields . In recent years , tungsten -copper composite material is gradually being used as cover material HEAT drug , its high density , high sound speed and good mechanical properties , help to improve HEAT Sunder power. Europe and other developed countries, studies show that, compared with the pure copper HEAT drug cover , tungsten -copper composite material cover the drug in the triple bombing high caliber of conditions, the armor depth can be increased by 30 %. With the continuous development of high-performance tungsten-copper composite materials preparation technology and applied research , and applications in the military industry will be more broad.

Tungsten-copper composite powder metallurgy materials is an important one of the widely used method for preparing a " Infiltration law ." The method is a mixture of tungsten powder, tungsten powder and a small amount of copper powder or pressed into the blank , by the pre- firing temperature for preparing a porous tungsten skeleton, and then the molten metallic copper and a capillary force to flow along the gap gradually tungsten particles fill skeleton obtained tungsten -copper composite material. Preparation of material dissolved infiltration with high density, good sintering properties , electrical conductivity, thermal conductivity , etc. ideal .

Due to the large gap between the melting point of tungsten and copper and immiscible , were prepared by powder metallurgy method of tungsten-copper composite material is often not high density , usually resulting in a conductive material , inadequate thermal and mechanical properties. In order to continue to meet the new requirements proposed industrial development , preparation techniques tungsten-copper composite task facing major reforms . In recent years , highly dispersed , the rapid development of nano- powder preparation techniques , new pressing and sintering technology , the performance of tungsten-copper composite gained further improved, effective broaden its application in high-tech fields.

Tungsten market : the market with ample supply of raw materials and scrap tungsten inquiry there , but the turnover has continued to light , tungsten, iron market demand is low, the downstream business procurement initiative is low, less market inquiry , coupled with the raw material of tungsten concentrate market downward , tungsten iron spot transactions also showed a stalemate , and the market is slightly weaker . Mainly because of the buyer to take advantage of weaker market outlook and weighed on prices ; seller tungsten market is still holding on long-term expectations and will ship is not strong. Both sides continued stalemate on the issue price , in the absence of external force , expected short-term dilemma is difficult to break the stalemate .

Molybdenum market : External molybdenum prices fell slightly , but the business mentality better, post-market is still strong side . Molybdenum domestic goods market continued to maintain silence, less early trading atmosphere . Foreign businesses not cheap , price stability, hold stocks wait and see. Admission is about to move steel , molybdenum market or expected short-term maintenance of stability persist run .

Today, the mainstream price of tungsten scrap market stabilize, ample supply , distribution of funds is tight . Because of funding constraints, the cash redemption price is down, the market price difference is widening, however, reluctant to hold stocks cheap goods to go , spot market transactions are not very active, expected short-term risk of tungsten steel scrap prices are still slightly downward .

It is understood by the price of cobalt and tungsten mine while lower impact materials , scrap tungsten drill mainstream has dropped 190 yuan / kg, and even some of the cash transaction price pressure as low as 185,186 yuan / kg, sold more than a lower price , but less volume .
