Black Tungsten Wire

All wires showed here are doped tungsten wires and manufactured by the high tech of doping, acid washing, isostatic pressing, PLC controlled direct sintering, swaging and auto feeding. Black tungsten wire products 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 tungsten wire weighing 5kg/pc. Customers are allowed to choose various types of black tungsten wire in accordance with their specific applications.

Type and Application of Black Tungsten Wire

Type  Application
STW91 Filament, shock-resistance filament and other high-temperature-resistance devices, ect
STW71 Auto lamp filament and other anti-shock devices
STW61 Coiled-coil filament, ect
STW31 Coiled-coil or trispiral CFL filament, incandescent filament and support, ect
STW41 Stranded tungsten wire, tungsten heater element, ect
