What Is Tungsten Nail Sinker? 10

Tungsten nail sinker is a fishing tool crafted from metal tungsten as the primary material, processed into a slender needle-like shape, and categorized as a subset of “sinkers” in fishing accessories. Its core feature leverages tungsten’s high density (approximately 19.3 g/cm3), achieving significant weight in a small volume while optimizing hydrodynamic performance post-entry into water. Compared to iron sinker: 1) Tungsten nail sinker has a higher specific gravity, resulting in a smaller volume at the same weight, reducing wind resistance…

Differences Between Tungsten Sinker and Lead Sinker 8

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 10

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? 11

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? 7

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…

Material Selection of Tungsten Wire for Glass Heating 7

Pure tungsten wire or doped tungsten wire is usually preferred for glass heating because of its high melting point, high temperature resistance and excellent stability. It is necessary to select the appropriate tungsten wire specifications according to the glass type, heating temperature and equipment design, and ensure that vacuum or inert gas protection is used to extend the life. For more specific suggestions and purchases, please contact CTIA GROUP (sales@chinatungsten.com). 1. Why Choose Tungsten Wire? 1.1 High Melting Point: The…

Precautions for Tungsten Wire in Glass Heating 10

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 12

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…

Information
Disadvantages of Tungsten Wire for Glass Heating 10

In the glass heating process, tungsten wire is often used as a heating element due to its high melting point, high temperature resistance, and good electrical conductivity. However, despite its excellent performance in some aspects, tungsten wire also has some significant disadvantages in practical applications, which may limit its widespread use in the field of glass heating. 1. Fragility Caused by Brittleness Tungsten is a metal material with high hardness but high brittleness. In glass heating equipment, tungsten wire may…
