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 |
| STW42 | Stranded wire, tungsten heater and other no special temperature required devices, ect |
| STW11 | Electrode and lead, ect |
The important applications of black tungsten wire are for the production of coiled incandescent lamp filaments, cathode and support structures for power tubes, heating elements for high temperature furnaces and evaporation sources in metallizing processes. Thicker wire sizes, straightened, finish-ground and cut into rod pieces are widely used for glass-to-metal seal lead parts in the lighting and electronic industries.
