    What Are the Main Uses of Tungsten Wire in Modern Industry?

    • Whats Tungsten?The Main Uses of Tungsten Wire 1. Incandescent LampThe Main Uses of Tungsten Wire 2. PhotocopierThe Main Uses of Tungsten Wire 3. HairdryerThe Main Uses of Tungsten Wire 4. Iodine-Tungsten LampThe Main Uses of Tungsten Wire 5. Charging LighterConclusionIt is mainly used as filament in an incandescent lamp. An incandescent lamp heats a tungsten wire to incandescence by means of heat radiation that emits visible light, and the filament in an incandescent bulb is made of ultra-thin tungsten wire. The normal working temperature of the lamp reaches more than 2000, which is not enough to reach the melting point of the tungsten wire 3370, but this high temperature can make a part of the tungsten wire surface atoms evaporate. The chemical Utilizing Tungsten Wire in Applications for General Aug 13, 2015 · For instance, tungsten filament wire is used as the electron emitter in devices such as scanning electron microscopes (SEMs), transmission electron microscopes (TEMs), and microprobes used in spectrometry systems. Due to its low coefficient of thermal expansion, the tungsten wire is able to maintain the correct shape for generating the electron What Is a Tungsten Filament? (with pictures)Light bulbs with a tungsten filament. A tungsten filament is a thin strand of the metal which glows very brightly when an electric current is passed through it. When coiled and sealed inside a glass container filled with an inert gas, a tungsten filament can glow brightly enough to light up a room. It was the inclusion of a tungsten filament in his electrical lighting system that resulted in the world giving
