Non - Sag Pure Tungsten Wire 218 Wires 0.04mm - 1.2mm For Bulb / Lamp Filament

Non-sag tungsten wire is also called doped tungsten wire or 218 tungsten wire. It is made from tungsten bars, mainly used in incandescent, halogen and other electric light sources. For a variety of light bulb for the tungsten wire, also need to mix a small amount of potassium, silicon and aluminum oxides.

Nowadays, non sag tungsten wire is generally made of a variety of drawing dies. The main application is to create the filament and high-speed cutting steel, also used in optical instruments, chemical apparatus and so on.

Brief Introduction of Non-Sag Tungsten Wires:


1. Purity: 99.95%
2. Grade: WAL1,WAL2, WAL3, WAL4 etc.
3. Density: 19.2g/cm3
4. The tungsten wire features excellent formability, long life and super lighting efficiency. Mainly used for making various electron tube, H series auto lamp,
halogen lamp and other special lamp

Applications of Non-Sag Tungsten Wires:

For producing heating elements and parts in vacuum furnaces

For producing electric light source parts and electric vaccum components
For producing heating elements used in vaccum metalizing or plating
Appearance: W-wire is regular black covered with graphite. After graphite is removed it is metallic luster.

Advantage of Non-Sag Tungsten Wires:

Non-sag tungsten wires are 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 deformation at high temperatures, high recrystallization temperatures, uniformity in dimension and excellent coilability.
