Quality
The wire must be subjected to tests - tensile and non-destructive electrical test. The material must meet the required mechanical properties - tensile strength, yield strength, relative elongation.
Use
BM grade is used in x-ray engineering and radioelectronics, for manufacturing of heaters and cathodes of electronic devices, which are designed for operation under conditions of vibration, shock, t° 2100 °C. Tungsten wires are used to manufacture cathodes for gas-discharge and electronic devices, bushings and other parts that do not require tungsten with special additives. Tungsten wire for lighting devices is produced in accordance with
