[Know Tungsten] Why is the Surface of Black Tungsten Wire Black? 108

The black surface of black tungsten wire is mainly because graphite emulsion is sprayed during the drawing process. As a lubricant, graphite emulsion can effectively reduce the friction coefficient between the tungsten wire and the drawing die, reduce the risk of tungsten wire breakage during the drawing process, and extend the service life of the drawing die. After the graphite emulsion adheres to the surface of the tungsten wire, a thin black coating will be formed, which is also the…

[Know Tungsten] Tungsten Wire for Photovoltaic Diamond Wire Saws 160

In the photovoltaic field, tungsten wire is generally used as a diamond wire base material for silicon wafer cutting. It has high toughness, high tensile strength, high temperature resistance, corrosion resistance and other characteristics. Compared with traditional high-carbon steel wire, tungsten wire has great potential for wire diameter refinement. At present, the diameter of tungsten wire used in diamond wire saws in the photovoltaic industry is about 25-35μm, which is only half the diameter of an adult hair. The diameter…

[Know Tungsten] Tungsten Wire for Electrically Heated Glass Windows 92

Tungsten wire is suitable for heating elements of electrically heated glass windows due to its high temperature resistance and resistance effect. Its working principle is to embed ultra-fine tungsten wire into the glass interlayer, generate resistance heat by powering on, and evenly heat the glass surface, thereby achieving functions such as rapid defrosting, anti-fogging and temperature regulation. This technology can be applied to automobile windshields and rearview mirrors, aircraft windows and smart glass for buildings.
