Photoelectricity Tungsten Wire

Introduction

Photoelectricity tungsten wire is mainly used in optical communications, laser, optoelectronic diaplay, optics, solar photovoltaic, electronic engineering, logistics network, and other fields for high melting point, high hardness and corrosion resistance of tungsten. Tungsten typically pull a variety of drawing dies system. The main application is to produce high-speed cutting steel, it also used in optical instruments, chemical equipment and others.

Photoelectricity, based on optoelectronics with comprehensive utilization of optics, precision machinery, electronics and computer technology to solve a variety of engineering application. Photoelectricity tungsten wire is to used as the filament in lamp. The higher the temperature of the radiating body, the more visible light component. Therefore, both luminous efficacy and brightness are higher. When the power supply voltage of photoelectricity tungsten wire is reduced, the filament temperature decreases, the visible spectral components weakened, luminous efficacy reduced.

Photoelectric tungsten wire resistivity is 5.3*10^(-8). Tungsten features a high melting point, high resistivity, good strength, low vapor pressure, it is the best material for all incandescent lamp. Most photoelectric tungsten wire production is used as ammonium paratungstate (APT) as raw material.
