Molybdenum Market – July 10, 2025 22

Molybdenum market update on July 10, 2025 The domestic molybdenum market is holding steady at high levels. Following a significant price surge for molybdenum products yesterday, raw material traders’ confidence in further price increases has weakened, with many adopting a wait-and-see approach. Meanwhile, downstream users are exercising caution toward high prices, leading to more conservative purchasing behavior. CTIA GROUP LTD views this as a normal market adjustment, suggesting that the trading sector needs time to digest the impact of recent…

[Know Tungsten] Why is the Surface of Black Tungsten Wire Black? 21

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 Electrically Heated Glass Windows 20

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.
