Black Tungsten Wires

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. The 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 tungsten wire in accordance with their specific applications.

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 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 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.
