7.1 Unalloyed and doped tungsten
In wire form, its main use is in the incandescent lamp industry. It is also used as a heating element for fluorescent tubes, lamp filament supports, electronic transmitters, electronic tube elements, vacuum metallization filaments (especially for aluminum: automobile headlights, capacitors, etc.), and heating elements for high-temperature furnaces. Tungsten rod is also used to make glass-to-metal joints, arc lamp electrodes and welding machine electrodes. Sheet metal is used to manufacture resistors and screens for high-temperature, vacuum or hydrogen industrial furnaces. Finally, tungsten is used to manufacture anticathodes for X-ray tubes and space rocket nozzles.
