Pure Tungsten Wire
Pure Tungsten Wire
Pure tungsten wire is selected for applications that require a high melting point, good electrical resistivity at elevated temperatures, and low vapor pressure. Its suitability depends on the operating environment, wire dimensions, and requirements of the finished component.

Applications of Pure Tungsten Wire
Pure tungsten wire is used in lamp filaments, vacuum components, heating elements, and high-temperature furnace assemblies. It is also used in selected electrical and electronic components where its thermal and electrical properties meet the design requirements.
The appropriate wire diameter, surface condition, and supply form depend on the component design and operating conditions. When requesting a quotation, please specify the required dimensions, quantity, surface condition, and intended application.
Surface of Tungsten wire
● Black wire with graphite
● Cleaned wire after pickling
● Electropolished bright wire
As we all know, the electronic tube and bulb industry needs a tungsten wire with a smooth surface and no graphite coating. This "white wire" is usually obtained by cleaning. The cleaning methods include chemical or electrolytic polishing, and acid or alkaline solutions. Among them, the electropolishing tungsten wire solution is the best
