Tungsten White Wire 0.1mm,0.2mm,0.3mm,0.5mm For Spring Filament Vacuum Electronic Device

Introduction

Tungsten stranded wire is a fine wire made of high-purity tungsten, known for its extremely high melting point, excellent electrical conductivity, and strong resistance to high temperatures.
It is widely used in applications that require stable performance under extreme thermal and electrical conditions.

Tungsten stranded wire can be classified into single-crystal and polycrystalline types:

Single-crystal tungsten wire is ideal for precision applications requiring high sharpness, such as electron sources in electron microscopes.

Polycrystalline tungsten wire is suitable for high-power applications such as electric heaters and lighting filaments.

Specification

Applications

1. Electric Heating Devices

Tungsten stranded wire is commonly used as a heating element in electric furnaces, oven heating tubes, and industrial heaters.
Its high temperature resistance, mechanical strength, and corrosion resistance allow it to perform stably for long periods in extreme conditions.

2. Lighting Industry

Tungsten wire is one of the most important materials in the lighting field, especially in incandescent and halogen bulbs.
Its ability to withstand high temperatures enables it to emit stable light and maintain durability during extended use.

3. Vacuum and Electronic Devices

In vacuum technology, tungsten wire is widely used in electron tubes, vacuum furnaces, and semiconductor devices due to its low resistance, high evaporation temperature, and long lifespan.

4. Aerospace and Industrial Fields

Tungsten stranded wire is also applied in rocket engine nozzles, superalloy production, fiber processing, and high-temperature furnaces, where superior thermal and corrosion resistance are required.
