White Tungsten Wire

What is white tungsten wire?

White tungsten wire is a tungsten wire whose surface has been electrolytically cleaned and polished. The surface of this tungsten wire is smooth, clean, uniform silver gray metallic luster, wire diameter uniform, good processing and forming performance, long life of the filament, high light efficiency. Widely used in the electric vacuum industry to produce various types of vacuum tubes. H series auto lamp, halogen lamp and other special lamp filament produced by electric light source industry.

1. High melting point and strength.
2. Low vapor pressure.
3. Highly resistant to corrosion and oxidation.
4. Good electrical conductivity.
5. Excellent thermal stability.

1. Used as filaments in incandescent lamps.
2. Used as heating elements in high-temperature furnaces.
3. Used in the production of electron tubes and electronic components.
4. Used in vacuum deposition processes for coating materials onto substrates.
5. Used in thermionic emission applications, such as cathodes in X-ray tubes.
