Wah tungsten

Technical characteristic

The material refers to technical tungsten. Melting point is 3380 °C, and boiling point is 5900 °C, while the evaporation rate remains minimal even at t° 2000 °C. Under normal conditions does not react with chemical reagents. Combines high hardness and high electrical resistance. It contains 0.03% molybdenum, thousandths of a percent calcium and iron. Aluminum and silicon are special technical additives.

Production

The technological ductility of tungsten is minimal, so semi-finished products are produced by powder metallurgy. At first, the powder metallurgy method produces a stack. After heating the stubic, is expanded on the rotary machine and bars with diameter of 2 - 3 mm are obtained, from which after drawing in hot state yarns with diameter of 0,2 - 0,3 mm are obtained.
