Types and Applications of Non-sag Tungsten Wire

Non-sag tungsten wire types and non-sag tungsten wire applications.

Type	Application
W61	Standard doped tungsten wire with excellent non-sagging property and high speed coil-ability, which can make filament for bulb lamps, auto lamps and fluorescent lamps.
W91	Excels in non-sagging property and fit for high temperature use, which can make filaments for halogen lamps, especially for high pressure halogen lamps.
WR15	WR15 wire has long time burning life and resistance to shock with excellent non-sag property for lighting,which is doped with K, Si, and Al compounds (AKS). Its property is much higher than W91 on life and resistance to shock.
HW31	Filament of fluorescent lamp and energy-saving lamp; HID electrode.
HW41	Heating resistor for vacuum metallization; heating materials in furnace; HID electrode; support wire.
HW42	Heating resistor for vacuum metallization; support wire.
HW61	Filament of incandescent lamp; fluorescent Lamp and energy-saving lamp; support wire; printer pins.
HW71	Anti-shock filament of auto lamp.
HW91	Filament of halogen lamp, high color temperature lamp and auto lamp.
HW99	Long-life filament of halogen lamp.

Type	Name	Kind	Application
WAl1	Non-sag tungsten wires	L	Used in making single coiled filaments, filaments in fluorescent lamps and other components
		B	Used in making coiled coil and filaments in high power incandescent bulb, stage decoration lamp, heating filaments, halogen lamp,special lamps etc.
		T	Used in making special lamps, exposition lamp of copy machine and lamps used in automobiles.
WAl2	Non-sag tungsten wires	J	Used in making filaments in incandescent bulb, fluorescent lamp,heating filaments,spring filaments, grid electrode, gas-discharge lamp, electrode and other electrode tubes parts.
