Production Steps of Tungsten Wire for Glass Heating 29

Tungsten wire is an ideal choice for glass heating applications due to its high melting point and high temperature resistance. The following is a brief overview of the main production steps for producing tungsten wire for glass heating: 1. Tungsten Ore Extraction and Refining: Tungsten trioxide (WO?) is extracted from tungsten ore (such as wolframite or scheelite). Impurities such as sulfur and arsenic are removed through chemical treatment (such as acid leaching and solvent extraction) to obtain high-purity tungsten trioxide.…

What Is Tungsten Nail Sinker? 33

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 34

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…

Information
Preparation Process of Tungsten Wire for Glass Heating 26

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? 36

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? 28

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…
