Tungsten Stranded Wire For Lamps And Vacuum Device Vacuum Coating

Introduction

Tungsten stranded wire is a fine wire made from high-purity tungsten. Due to its extremely high melting point, excellent strength, and superior resistance to corrosion, it is widely used in applications that operate under high-temperature and high-stress conditions.

Tungsten stranded wire is typically divided into two types:

Single-crystal tungsten wire – used in applications that require high precision and sharpness, such as electron sources in electron microscopes.

Polycrystalline tungsten wire – used in high-power electrical devices such as electric heaters and lamps.

Specification

Applications

1. Electric Heating Devices
   Tungsten stranded wire is widely used as a heating element in electric furnaces, oven heating tubes, and industrial heaters. Its high strength, high temperature resistance, and corrosion resistance allow it to operate stably in harsh environments for extended periods.

2. Lighting Industry
   Tungsten wire is an essential component in incandescent and halogen lamps. Its excellent thermal stability and durability enable it to emit light efficiently and consistently at high temperatures.

3. Vacuum Devices
   Tungsten wire is commonly used in electron tubes and vacuum systems due to its low resistance, high evaporation temperature, and long operational life. It is also a key material in electron emission applications.

4. Other Applications
   Tungsten wire is also used in rocket nozzles, fiber processing, and superalloy production, where high temperature, strength, and corrosion resistance are required.

Advantages

1. Excellent High-Temperature Resistance
   Tungsten wire has an exceptionally high melting point (up to 3422 °C), making it ideal for extreme thermal environments.

2. High Strength
   The strong metallic bonds in tungsten give it outstanding tensile strength, maintaining stability under high mechanical loads.

3. Good Corrosion Resistance
   Tungsten performs well in various acidic and alkaline environments, ensuring longevity in corrosive conditions.

4. Long Service Life
   Tungsten wire offers excellent durability, operating reliably and efficiently for long periods even under extreme temperatures.

Baoji City Changsheng Titanium Co.,Ltd is registered in 2006. Registered capital of 10 million yuan, the legal person is Zhao Wenhua. Before 2006, the factory is formed as forged workshop, no been registered. The year of 2006 was exist as a starting for Changsheng Titanium Co. The factory is located in today’s No.26 Baotai Road Weibin District, Baoji City,Shaanxi Province.
