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 in use, but only 3% of all uses of tungsten), also widely used carbide tools (half of Kekai tungsten alloy is used for this purpose), oil and gas exploration in the "hard steel" drill, rocket engine nozzle and cathode-ray tubes, 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 ball 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 balls 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.
Very nice post thanks for sharing it. tungsten ball
