Wolfram W Tungsten Filament

Wolfram W Tungsten Filament Information

The production process of this wire material includes: preparing high-purity tungsten material-pressing-molding-sintering-drawing-twisting-surface polishing.

After wire drawing, multiple tungsten wires need to be twisted according to certain rules. The twisting method and number of strands depend on the purpose and requirements of the product. The process requires the use of special twisting equipment to ensure the quality and uniformity of the twisted wire by accurately controlling the twisting speed and tension.

Advantages

• High melting point, very good dimensional stability at high temperature, strong corrosion resistance.
• High hardness, good wear resistance, and deformation resistance.
• Excellent conductivity, able to effectively transmit current.
• High thermal conductivity can conduct heat and dissipate heat at high speed.
• Low vapor pressure, not easy to volatilize during operation, long service life.

Application

Wolfram W Tungsten Filament is most commonly used in the lighting industry, high-temperature heating industry and electronic equipment. It can achieve the purpose of power generation, heating and lighting, and is further used in different industries such as metal smelting, ceramic firing, aerospace, flat-panel displays, medical devices, etc.

• This material is used as the filament in incandescent and halogen tungsten lamps, enhancing both the lifespan and the luminous efficiency of the filament.
• This wire serves as a cathode in electron tubes, emitting high-energy, stable electron beams that ensure efficient tube operation.
• These heating elements are used in high-temperature electric furnaces, including resistance, vacuum, and induction furnaces, to efficiently conduct heat and ensure the smooth progression of the processing.

Usage and storage recommendations

When using Tungsten Filament, control the heating and cooling rates to avoid mechanical damage. It should be stored in a dry, ventilated environment, avoid moisture and corrosive gases, and must be inspected and cleaned regularly.
