Insufficient global supply of tungsten growing trend

Tungsten is one of the world most hard materials texture , this metal to extreme heat - especially high- calorie - has a remarkable capacity, in addition to the vacuum tube filament incandescent filament outside ( the latter is indeed still use, but only 3% of all uses of tungsten ) , also widely used carbide tools ( half of tungsten is used for this purpose ) , oil and gas exploration in the " hard steel " drill , rocket engine nozzle and a cathode ray tube, an irreplaceable importance.

Tungsten is being increasingly applied to new technologies. High hardness, high stability and ability to withstand extreme temperatures they have , making it an ideal material for the electrodes and components used in touch screen . With smart phones and tablet devices for explosive applications touchscreen technology, the world demand for tungsten in the original annual growth rate of 6% on the basis of further surge.

China's tungsten production accounts for over 80% of world production , has slashed exports of tungsten , has now become a net importer of this precious metal. The control of exports of tungsten did not show any signs of loosening , which was used for the country's manufacturing sector . Therefore , the rest of the world will find another new sources of supply .

Russia has some reserves , but will remain 70% for domestic use . People also recovered from the use of existing equipment and spare parts in tungsten , but even this source has now also applied to the limit, for the time being there is no sufficient new resources appear.

Right now, the removal of China and Russia , only five tungsten mine as a major supplier of the global market. A recent British Geological Survey report released a list of the existence of the economic value of the metal , " endangered " , which topped the list of tungsten .
