What Is Bullet-Shaped Tungsten Sinker? 9

Bullet-shaped tungsten sinker is a high-performance tool in modern fishing, typically composed of tungsten, nickel, and iron, with a density ranging from 16.5 to 18.75 g/cm3—significantly higher than that of lead sinker (approximately 11 g/cm3). At the same weight, tungsten sinker has a smaller volume than lead sinker, reducing water resistance and enabling faster sinking to the target water layer. Additionally, tungsten sinker is non-toxic and non-radioactive, replacing lead sinker to mitigate pollution risks to water bodies and aquatic life.…

Why Choose Tungsten Wire for Heating Glass? 5

The reason for choosing tungsten wire as a heating element when heating glass is mainly based on the unique physical and chemical properties of tungsten. First of all, tungsten has an extremely high melting point of about 3422°C, which is one of the metals with the highest melting point in nature. Glass processing (such as melting, forming or annealing) usually needs to be carried out in a high temperature environment. Tungsten wire can withstand high temperatures above 1000°C without melting…
