Classification	Characteristics	Applications
W31	Standard doped tungsten with excellent non-sagging property.	Filaments for bulb lamps and fluorescent lamps, heaters for electron tubes.
W41	Tungsten wires with re-crystallization point lower than that of W31 and excels in reforming.	Vacuum metalizing material and high temperature structural material.
W91	Excels in non-sagging property and a best fit for high temperature use.	Filaments for halogen lamps.
W99	Tungsten wires with re-crystallization point higher than that of W91 and excels non-sagging property	Filaments for halogen lamps with longer life.
WKMT10	Thoria Tungsten Wire (and Rods). Commonly used in inert gas welding (TIG) and plasma welding. Can carry 50% more current than tungsten, and produces a more stable arc.	Prematerial for lamp electrodes are available at diameters from 0.25 to 2 mm. Filaments for magnetrons for microwave ovens
