The application of tungsten in china

         Now China tungsten application, roughly divided into four categories:1.Used for cutting, wear, welding and spraying of carbides. The mining industry and the oil industry make extensive use of tungsten carbide, mainly for drill bits, bulldozers and crushers. Tungsten carbide is also widely used in wear parts of transport and electrical equipment.

  2.For the electrical and electronics industries. In the electronics industry, a large number of filament and the cathode of the tube, the electrical contact of the car, the heating element of the high temperature resistance furnace, the balance hammer and the pendulum used in the aerospace industry, all from the tungsten processing.

  3.For high-speed steel, tool steel, die steel, high temperature and high strength alloys and a variety of non-ferrous metal alloys. Add other metal tungsten alloy is widely used in the field of high temperature, as well as military production armor piercing and so on.

  4.For a variety of chemical products. Tungsten in the textile dyes, paint pigments, ceramic glaze, toner and glass coloring and other light industry applications have a vast world. TV picture tube, X-ray phosphor screen and fluorescent fluorescent materials, etc., are selected tungsten compounds. Tungstophosphate is used as a corrosion inhibitor and a fire retardant for the textile industry. Used in the manufacture of oil refining contact with coal.
