[Know Tungsten] What is Cleaned Tungsten Wire? 133

Cleaned Tungsten Wire, also known as white tungsten wire, does not refer to tungsten wire with a white surface, but refers to tungsten wire that has been electrolytically washed and polished. The surface of this tungsten wire is smooth and clean, without graphite emulsion attached, and presents a silver-gray metallic luster. Cleaned Tungsten Wire has uniform diameter, good processing and forming performance, long life, and high light efficiency. It is widely used in various types of electric vacuum devices as…

[Know Tungsten] Why is the Surface of Black Tungsten Wire Black? 111

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 164

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 94

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.

Rare Earth Market – July 9, 2025 185

Rare earth market update on July 9, 2025 The domestic rare earth market continues to operate with a strong upward trend, driven by increased downstream demand, limited growth in spot supply, and persistently high overseas rare earth prices. Many suppliers are reluctant to sell and are raising prices. However, price trends for mainstream light and heavy rare earth products show some divergence: praseodymium-neodymium (PrNd) prices have seen expanded gains today, while dysprosium-terbium (DyTb) prices remain stable. Currently, praseodymium-neodymium oxide and…
