Technical characteristics

Tungsten VA is a high purity metal which contains not less than 99.999%, tungsten. This metal is used for the manufacture of tungsten electrodes and current-carrying parts is particularly durable, high-intensity discharge lamps. V. A. tungsten is also used as nepalaya targets for the deposition of films in semiconductor devices. This purpose of the material powder is prepared, and screws for the electrodes. Chemically pure tungsten is the basis for the production of tungsten-titanium or tungsten-silicon wafers by vacuum hot pressing.

Application

Profile rolled tungsten brand WA (rods, circle, rods, etc.) is used as the heat-conducting elements of different equipment, in particular, crankshafts and cylinders of high-speed cars, successfully replacing the heat-resistant stainless steel. Tungsten rods high purity is also widely used in guns, rockets, satellites, aircraft and ships.
