Application of Tungsten Tube

Tungsten tube, also known as tungsten rod, is a versatile material that finds application in a wide range of industries. Some of the common applications of tungsten tube are:

  • Lighting industry: Tungsten tubes are widely used in the manufacture of incandescent light bulbs. The tungsten filament inside the bulb is made from a tungsten wire that has been drawn down to a very fine diameter and coiled into a tight spiral.

  • Electronics industry: Tungsten tubes are used as electron emitters in a variety of electronic devices, such as cathode ray tubes (CRTs) and X-ray tubes. They are also used in the manufacture of electronic contacts, heating elements, and vacuum systems.

  • Aerospace industry: Tungsten tubes are used in the manufacturing of aerospace components, such as rocket nozzles, airframe components, and hot section components in gas turbine engines.

  • Medical industry: Tungsten tubes are used in the manufacture of medical equipment, such as X-ray machines and radiation shields.

  • Defense industry: Tungsten tubes are used in the manufacturing of ammunition for armor-piercing shells and bullets.

  • Chemical industry: Tungsten tubes are used in chemical processing equipment, such as reactors and heat exchangers, due to their excellent corrosion resistance and thermal stability.

  • Glass manufacturing industry: Tungsten tubes are used as electrode material in glass melting furnaces, due to their high melting point and chemical stability.

  • Automotive industry: Tungsten tubes are used in the manufacturing of high-performance parts, such as spark plug electrodes, due to their excellent electrical conductivity and heat resistance.

Specifications of Tungsten Tube

The specifications of tungsten tube can vary depending on the manufacturer and the intended application, but some general specifications include:

  • Diameter: Tungsten tubes can have diameters ranging from a few millimeters to several centimeters, with typical diameters being between 1mm to 25mm.

  • Length: Tungsten tubes can have lengths ranging from a few centimeters to several meters, with typical lengths being between 50mm to 300mm.

  • Purity: Tungsten tubes are available in different purity levels, with high purity grades being up to 99.99%.

  • Density: Tungsten has a high density, which can range from 17 to 19.3 g/cm³.

  • Surface finish: Tungsten tubes can have a variety of surface finishes, including ground, polished, or chemically treated surfaces.

  • Tensile strength: Tungsten has a very high tensile strength of up to 500 MPa.

  • Thermal conductivity: Tungsten has a high thermal conductivity of up to 174 W/mK.

  • Melting point: Tungsten has a very high melting point of 3,422°C.

  • Chemical resistance: Tungsten is highly resistant to corrosion and chemical attack, making it suitable for use in harsh environments.

These specifications can be tailored depending on the specific requirements of a particular application.
