Tungsten sinker and lead sinker are both common fishing weight tools, available in shapes like teardrop, cylindrical, and olive forms. However, they differ across multiple dimensions, including production costs, materials, performance, and manufacturing processes.

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:

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:
