Relevance
Manufacture of wire by the powder metallurgy method, intended for the production of electronic devices and light sources. It is necessary to consider the complexity of processing, which is due to the exceptional refractoriness and hardness of the material. Also, the disadvantages of tungsten include the difficulty of mining it and obtaining pure material. Under natural conditions, tungsten is tough and brittle.
Percentage composition of W-10 GOST 19671-91
| W | Impurities | Total |
| min 98.46 | ≤ 0.05 | 1.0 = |
Advantages
High resistance to thermal creep, inertness in concentrated acids, alkalis and other aggressive media.
Production and applications
Tungsten wire is the most relevant product. Under normal circumstances, the technological ductility of tungsten is insufficient, but when the temperature increases, it increases without loss of strength. For this reason, the rolled product is obtained using the hot work method under pressure. The diameter of this product ranges from 25 to 1500 microns and is mainly used in the manufacture of cathodes for electronic, gas-discharge devices.
