Manufacturing by powder metallurgy of the wire, intended for the production of electronic devices and light sources. Consider the complexity of the processing, which is necessary due to the extreme refractoriness and hardness of the material. Another disadvantage of tungsten include the complexity of its production and obtain pure material. In natural conditions, tungsten is characterized by rigidity and fragility.
The percentage composition of W-15 GOST 19671−91
