W1 W2 Tungsten-stranded Wire For Vacuum Plating Heater High Temperature Resistance

Introduction

Tungsten stranded wire is a fine wire made of high-purity tungsten, known for its extremely high melting point, excellent electrical and thermal conductivity, and outstanding strength.
It is widely used in applications that require stable operation under high-temperature and high-stress environments.

Tungsten stranded wire can be classified into two types:

Single-crystal tungsten wire: suitable for precision applications such as electron sources in electron microscopes.

Polycrystalline tungsten wire: ideal for high-power electrical applications, including electric heaters and lamps.

Specification

Applications

1. Electric Heating Devices

Tungsten stranded wire is widely used as a heating element in electric furnaces, ovens, and industrial heating tubes.
Its high melting point, mechanical strength, and corrosion resistance make it ideal for long-term stable operation under extreme conditions.
