Wire rod produced by powder metallurgy. First get the rod billet, after which it is heated, forged in the forging of a special rotary machine and get bars with a diameter of 2−3 mm. subsequently, the rods pulled into a thin thread with a diameter of a few microns.
In electrical engineering, electronics are made of mesh, the filament heaters of the cathodes for cathode ray tubes; thermionic generators, and other similar devices. In measuring instruments for the high temperatures (about 2500°C) used thermocouple alloys of tungsten and rhenium. They are much more conventional thermocouples of molybdenum and tungsten. Termoelektrodny the wire is made of tungsten alloy with rhenium BP-27, BP-20 (rhenium — 20%), BAP-5 (Tungsten-rhenium thermocouples are manufactured in molybdenum or ceramic covers.
