Non-sag Tungsten Wire

Definition of non-sag tungsten
Non-sag tungsten is tungsten doped with the element of K (potassium) or other elements to achieve the effect of non-sag of the tungsten wire. Doping with K can form bubbles in tungsten wire, which can prevent the recrystallization of the tungsten wire. And they are also responsible for their outstanding low resistance of non-sag tungsten at high temperatures of a glowing lamp filament. About 90% of non-sag tungsten is used in incandescent lamps.

Definition of non-sag tungsten wire

Non-sag tungsten wire is applied the material of non-sag tungsten so that the tungsten wire shares the properties of non-sag tungsten. They can be less shakable when used in light sources or heating elements for the dopant material used in non-sag tungsten wire.
