The manufacturing process of strand tungsten filaments involves several key steps, each of which significantly influences the filament's final properties, such as its strength, conductivity, and heat resistance. Below is a typical process for manufacturing tungsten filaments and how each stage impacts the properties of the filaments:

Analysis of latest tungsten market from Chinatungsten Online

China tungsten price is generally in a weak and stable deadlock stage, mainly due to increasing pressure on the demand side, which is exacerbating, and the recent rise in supply-side profit-taking, 

The durability and longevity of strand tungsten filaments in high-temperature environments are influenced by several key factors that determine their ability to withstand extreme heat, mechanical stress, and chemical reactions. Below are the primary factors that contribute to the performance and lifespan of tungsten filaments in such conditions:

Chinese rare earth prices remain stable in certain segments, with slight declines in others. Prices for gadolinium oxide, terbium oxide, and holmium oxide have dropped by approximately 4,000 RMB/ton, 40 RMB/kg, and 20,000 RMB/ton, respectively.
