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.
