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.

The packaging of tungsten wire for glass heating usually needs to consider factors such as high temperature tolerance, oxidation resistance, moisture resistance, and transportation safety. The following are some common packaging methods and precautions:

The transportation of tungsten wire for glass heating needs to pay special attention to its physical properties and safety requirements. The following are relevant suggestions:

The quality control of tungsten wire for glass heating involves multiple key links such as raw materials, production, and testing to ensure its stable performance, high temperature resistance and long service life.
