Introduction

Tungsten stranded wire is a fine metal wire made primarily of tungsten. Due to its extremely high melting point, excellent electrical and thermal conductivity, and superior mechanical strength, it performs reliably in demanding high-temperature environments.

Tungsten stranded wire is available in two main types:

Single-crystal tungsten wire — used in precision applications such as electron sources in electron microscopes.

Polycrystalline tungsten wire — used in high-power electrical applications, such as electric heaters, lamps, and other heating devices.

Specification

Application

1. Electric Heating Devices
   Tungsten stranded wire is widely used as a heating element in electric furnaces, ovens, and industrial heaters. Its high strength and corrosion resistance enable stable performance in long-term high-temperature service.

2. Lighting Industry
   Tungsten wire is a key material in incandescent and halogen lamps. Its high melting point and durability ensure stable, long-lasting light emission under high operating temperatures.

3. Vacuum Devices
   In vacuum and electronic technology, tungsten wire is used in electron tubes, semiconductor components, and vacuum furnaces due to its low resistance, high evaporation temperature, and long service life.

4. Aerospace and Industrial Applications
   Tungsten wire is also applied in rocket nozzles, fiber processing, and superalloy manufacturing, where high temperature, high strength, and corrosion resistance are critical.
