Black Tungsten Wires


black 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.

Type & Application of black tungsten wires

Type Application
STW91 For making filament, shock-resistance filament and other high-temperature-resistance devices, ect
STW71 For making auto lamp filament and other anti-shock devices.
STW61 For making coiled-coil filament, ect.
STW31 For making coiled-coil or trispiral CFL filament, incandescent filament and support, ect.
STW41 For making stranded black tungsten wire, tungsten heater element, ect. .
STW42 For making stranded tungsten wire, tungsten heater element and other no special temperature required devices, ect.
STW11 For making electrode and lead, ect.

The important applications of black tungstne wires 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.
