According to foreign media reports, one of the reasons is located in southwest England Devon Homerden project began to cause attention, this is the first New England 45 years enabled, but the more important reason is that it will produce tungsten, that is to say it will provide sufficient sources of tungsten to tungsten carbide powder production.Or will weaken the Chinese domination of the tungsten carbide powder.

Two years ago, the British geological survey evaluation study on tungsten supply risk level highlights the importance of tungsten, at the highest risk level is 10, Institute of geological survey score of 9.5, with the same rare risk level, because these two kinds of resources production and consumption were China led, can Chinese decided to supply other countries. In order to improve the situation of tungsten carbide powder resources to speed up the British defect research and development of mineral products, and the discovery of new mines cleared the financial barriers, provide adequate sources of tungsten to tungsten carbide powder production, from the economic point of view, new mines will bring in huge profits.

Mainly used in the production of tungsten carbide. Widely used in metal cutting tools, mining and geological drill insert, tensile stamping die,wear resistant and corrosion resistant parts. Tungsten carbide and tungsten carbide powder,which are made by melting casting tungsten carbide alloy. For surfacing wear resistance of parts or products, can prolong the service life. Tungsten alloy used in the manufacture of high-speed drill, wear, cutting tools and machinery in the anti strike, structure corrosion resistant material. The high proportion alloy made of iron nickel copper manganese tungsten containing high, to balance the system and weight system of the aircraft, the rotor inertial rotation element and gyro instrument system, and medical and chemical radioactive isotope (Co 60) of the container. The other tungsten compound used in paint, paint, rubber, textile, petroleum, chemical industry and so on. The use of tungsten is still expanding, such as: high temperature in metallurgy The coating for the oxidation; the aerospace industry as a rocket nozzle, nozzle, heat exchanger dissociation ion rocket engine; used as a container of liquid metal tungsten thermionic nuclear engineering, switches and so on.
