Tungsten wire ¡¡¡¡

¡¡Product Feature ¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡

Doped tungsten wires are manufactured by the high tech 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 remprrtallization temperatures, uniformity in dimension and excellent cofiability. For tungsten rod weighing 3kg/pc, its rough welding tungsten wire weighing 5kg/pc, this technology takes lead in China. Customers are allowed to choose various types of tungsten wire in accordance with their specific applications.
