Differences Between Tungsten Sinker and Lead Sinker 7

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. I. Material Aspects Tungsten sinker is an alloy primarily composed of tungsten (85%–99%) with small amounts of nickel, iron, and other metals, designed for fishing. Lead sinker, also known as a lead weight, is made mainly of lead or lead-tin alloys and is an essential auxiliary…

Preparation Process of Tungsten Wire for Glass Heating 9

The preparation process of tungsten wire for glass heating mainly involves the purification, processing and subsequent treatment of tungsten materials to ensure that it has excellent performance at high temperatures and is suitable for high-temperature environments such as glass heating. The following is a typical process flow for the preparation of tungsten wire: 1. Raw Material Preparation Tungsten Ore Purification: The preparation of tungsten wire starts with tungsten ore (such as wolframite or scheelite), and extracts high-purity tungstic acid or…

What Is Bullet-Shaped Tungsten Sinker? 10

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? 6

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…

Precautions for Tungsten Wire in Glass Heating 8

Tungsten wire, as a high melting point and high temperature resistant material, is often used in glass heating processes such as glass melting, forming or annealing. However, when using tungsten wire for glass heating, you need to understand the following precautions to ensure safety, efficiency and extend the life of the equipment. 1. Prevent Oxidation: Tungsten wire is very easy to react with oxygen at high temperature to form tungsten oxide, resulting in embrittlement or fracture. Therefore, the heating process…

Safety of Tungsten Wire for Glass Heating 10

Tungsten wire is safe to use as a heating element in glass heating, but the premise is that the use environment is controlled (vacuum or inert atmosphere), the equipment is well maintained, the operation is standardized, and appropriate protective measures are provided. 1. High temperature safety: Tungsten wire has an extremely high melting point and is suitable for high temperature processes such as glass melting or molding. However, its operating temperature is often far higher than the softening point of…

The Principle of Tungsten Wire Heating Glass 8

The principle of tungsten wire heating glass is based on the scientific mechanism of electrothermal conversion and heat transfer. Its core is to efficiently convert electrical energy into thermal energy, and act on the glass through a specific heat transfer method to make it reach the temperature required for processing or molding. This process combines the characteristics of electrical energy, thermal energy and material science, and is widely used in glass manufacturing, light bulb production and industrial heat treatment. 1.…
