What are the main characteristics of tungsten wire? In which industries are these characteristics mainly used?

Physical properties of tungsten wire:

High melting point: Tungsten has a melting point of up to 3410°C, one of the highest of all metals, which allows tungsten wire to remain stable in extremely high temperature environments without melting or deforming, making it very suitable for use in extremely hot environments, such as light bulb filaments and high-temperature furnaces.
In addition, tungsten wire has high tensile strength, especially at high temperatures, and has excellent corrosion resistance, which allows it to maintain stability in harsh chemical environments. It is also a good conductor of electricity, which is very beneficial for electronic applications.

High density: Tungsten has a density of 19.25g/cm³, which is one of the high-density materials. In some applications that require counterweight or high-density characteristics, such as radiation protection materials, sports equipment, etc., tungsten wire has significant advantages.

Low thermal expansion coefficient: Tungsten wire has a low thermal expansion coefficient, which means that it has less dimensional changes when the temperature changes. This feature helps to improve the stability of the equipment and reduce thermal stress caused by temperature changes, and is suitable for the manufacture of precision instruments and equipment.

Good ductility: Tungsten wire can be made into extremely fine wires with a diameter of several microns by stretching and cold working, but it does not affect the hardness of the tungsten wire. This property makes tungsten wire suitable for application scenarios that require fine structures, such as microelectronics, optical fiber communications, aerospace and medical equipment.

Introduction to the mechanical properties of tungsten wire

High strength and hardness: Tungsten wire has high tensile strength and hardness, and can maintain good mechanical properties even under high temperature conditions. This makes tungsten wire perform well in scenarios that require wear resistance or high strength, such as making high-strength fibers or for cutting tools.

Good creep resistance: Tungsten wire has a low creep rate at high temperatures, which means it can maintain stable performance in a long-term high-temperature working environment. This feature is critical to ensuring the long-term reliability of equipment at high temperatures.

 

Electrical properties of tungsten wire

Good conductivity: Tungsten wire is an excellent electrical conductor with a resistivity of 5.3×10⁻⁸. Although it is higher than copper and other metals, in practical applications, this property enables it to generate enough heat when current passes through it, so that the light bulb glows. It is widely used in wires, electrodes and other parts of electronic components.

High resistance performance: Tungsten wire has a higher resistance performance, so that it generates more heat than other metals under the same power-on time, which can meet the heat generation required for the filament to glow.

 

Chemical properties of tungsten wire

Corrosion resistance: Tungsten wire has good corrosion resistance to most chemical substances, especially in high temperature environment, it can form a protective oxide layer, which can maintain its chemical stability. This makes tungsten wire have a wide range of application prospects in the chemical industry, aerospace and medical fields.

High temperature oxidation resistance: At high temperatures, a dense oxide film will form on the surface of tungsten wire, which can prevent the internal tungsten from being further oxidized, thereby ensuring the stability and service life of tungsten wire in high temperature environment.
