The wire should be subjected to the tests — tensile and non-destructive electric test. The material must meet the required mechanical properties — the tensile strength of tensile, yield strength, elongation.
Mark WM used in x-ray technology and electronics, for manufacturing heaters and cathodes for electronic devices that are designed to operate in conditions of vibration, shock, t° 2100 °C. of the wire is made VRN cathodes of gas-discharge and electronic devices, bushings and other parts that do not require tungsten with special additives. Tungsten filament for lighting devices made in accordance with GOST 19 671−91 with a diameter of 19.5 microns — 1.5 mm. This wire is used for the production of surgical instruments, parts of missiles, aircraft, textile machinery.
