The material belongs to the technical tungsten. The melting point is equal to 3380 °C, boiling point is 5900 °C, the evaporation rate is minimal even at a temperature of 2000 °C. under normal conditions does not react with chemical reagents. Combines high hardness and high electrical resistance. In the composition of the 0.03% molybdenum thousandths of a percent of calcium and iron. Aluminium and silicon are the special technical additives.
Technological plasticity of tungsten is minimal, so the semi-finished products are produced by powder metallurgy. First, by powder metallurgy get Fort. After heating the rod billet, Raskulinecz on a rotating machine — get bars with a diameter of 2 — 3 mm, of which after drawing in the hot condition getting the filament diameter of 0,2 — 0,3 mm.
