Pure Tungsten Wire for Lights WAL Wires made by Virgin Tungsten Material

 

Tungsten WAL wire is also called Al Doped Tungsten Wire, non-sag tungsten wire. It is drawed from forged tungsten bars with good high temperature performance and high purity. It's generally used for lights, such as incandescent, halogen and other electric light sources.

 

For a variety of light bulb for WAL wires, also need to mix a small amount of potassium, silicon and aluminum oxides. Nowadays, the WAL wires can be made by 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.

 

Properity of Tungsten WAL Wires:


1. Purity: 99.95%
2. Grade: WAL1,WAL2, WAL3
3. Density: 19.1g/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
 

Advantage of Tungsten WAL Wires:

                                             
Tungsten WAL 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.
