Характеристики

High purity twisted stranded W Tungsten filament is spooled on clean, defect free spools. For very large diameters, tungsten wire is self coiled. Spools are level filled without piling near flanges. The outer end of the wire is properly marked and attached securely to the spool or self coil.

 

W Tungsten filament product feature:
 Doped tungsten wires are manufactured by the high technology of doping,acid,washing, isostatic pressing, PLC controlled direct-sintering, swaging and auto feeding. The products are featured with minimum deformation at high temperatures, high recrystallization temperatures, uniformity in dimension and excellent coilability.

Diameter:φ0.0020-1.8mm
Use: Used for making stranded(spiral) tungsten wire, tungsten heater elements, filaments, lamp filaments, coiled –coil filaments, support , electrode and lead etc.
