tungsten wire
All wires showed here are black tungsten wires and manufactured by the high tech of doping, acid washing, isostatic pressing, PLC controlled direct sintering, swaging and auto feeding. Black tungsten wires are featured with minimum formation at high temperatures, high recrystallization temperatures, uniformity in dimension and excellent coil ability. For tungsten rod weighing 3kg/pc, its rough welding black tungsten wire weighing 5kg/pc. Customers are allowed to choose various types of black tungsten wire in accordance with their specific applications.
