Tungsten is used extensively for filaments for electric lamps, electron and television tubes, and for metal evaporation work; for electrical contact points for automobile distributors; X-ray targets; windings and heating elements for electrical furnaces; and for numerous spacecraft and high-temperature applications. High-speed tool steels, Hastelloy(R), Stellite(R), and many other alloys contain tungsten.
Brief Introduction of Tungsten Wire:
1. Purity: 99.95%-99.98%;
2. Grade: W1, W2
3. Density:19.2g/cm3
4. Appearance: black surface
5. Supply state: annealing
6. 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 Black Tungsten Wires:
• Tungsten heater element
• Other heater components in semiconductor
• High temperature lamp and filament, stock - resistance filament, double helix filament etc
• Electric incandescent lamp filament, fluorescent light filament, etc
Packing of Tungsten Wire:
• Tungsten wire in spool: plastic case or plastic vacuum packing.
• Tungsten wire in coil: woven bag or plastic vacuum packing.
Note: The length or weight of single tungsten wire can be supplied by your special request.
