Since Edison invented filament lamp, tungsten has been applied in the field of lighting for more than 100 years. From the initial thermal radiation source to the more efficient gas discharge light source, tungsten’s core position in the electric light source has never wavered.
The emergence of electroluminescent light source has subverted the general understanding of the electric light source material, but tungsten as the core material of the electric light source will exist for a long time.
Tungsten materials are also widely used in a variety of electric vacuum devices, including magnetron, high-voltage rectifier.
Zhengzhou Sanhui Co., Ltd offers core components of electric light source products, like high pure tungsten rod, tungsten wire and tungsten alloy products. We also provide tungsten customized products according to drawings.
