Doped tungsten wire is added silicon and aluminum oxide into the tungsten wire.

The manufactuere pross of doped tungsten wire are high technology of doping,isostatic pressing, aciding washing,program control direct sintering, auto feeding and swaging.

Doped tungsten wire property:
high temperature resistance and minimun deformation at high temperature; good resistance to vibration; high recrystallization temperature; good coil ability, etc;

Application of doped tungsten wire property:

*Doped tungsten wire are mainly used for lighting lamps.

*Used as supports in all incandescent;

*Applicated for high temperature halogen lamps;

*Applicated for electronic tube and heater.
