High Purity Tungsten Wire

High Purity Tungsten Wire

Most of the high purity tungsten wires are produced using ammonium para tungstate as raw material. The general process are to roast ammonium para tungstate in the air at about 500°C to tungsten trioxide or to reduce it slightly to blue tungsten oxide in hydrogen at about 450°C. They are mainly used as high-temperature heaters and high-temperature structural parts. They are mainly used as high-temperature heats generators and high-temperature structural parts.

Product Introduction

High purity tungsten wires can be used to make direct hot cathodes and grids for electronic oscillation tubes and side hot cathode heaters in various electronic instruments. The properties of tungsten also make it suitable for TIG welding and other such work where the electrode material can also be used for high-speed cutting of alloy steel, super-hard molds, optical instruments, and chemical instruments. Tungsten monomer is a silvery-white lustrous metal with high hardness, high melting point, not subject to air erosion of room temperature, and relatively stable chemical properties. 


The pure tungsten wire produced by Yusheng Metal is made of high purity tungsten powder. As the most refractory metal tungsten is a component of many thermally strong alloys and is mainly used for strongly wear-resistant parts, such as flaps of aero-engines, working parts of die-cutting hot cutters, turbine impellers, excavation equipment, surface coating into plows. Alloys of tungsten and other refractory metals (e.g. tantalum, niobium, molybdenum, rhenium) are used as thermally strong materials in aerospace rocket technology, as well as in other sectors requiring high thermal strength for machine parts, engines, and some instruments.


Tungsten wires is widely used as electric vacuum lighting materials, gate switches, circuit breakers, spot welding electrodes, and other working parts of very effective contact materials.
