Characteristics of Tungsten Wire

The main characteristics of tungsten wire are as follows:

High Melting Point: Tungsten has an extremely high melting point of about 3422°C, the highest of all metals, and is suitable for use in high temperature environments, such as incandescent bulbs and electron tubes.

High Density: The density of tungsten is 19.25 g/cm³, close to gold, which gives it high mechanical strength.

Excellent High Temperature Resistance: Tungsten wire can still maintain stable physical and chemical properties at high temperatures and is not easy to deform or melt.

Good Electrical and Thermal Conductivity: Tungsten wire has moderate electrical conductivity and good thermal conductivity, and is suitable for use as an electric heating element.

Corrosion Resistance: Tungsten has good corrosion resistance to most chemicals, especially in non-oxidizing environments.

High Hardness and Strength: Tungsten wire has high hardness and tensile strength, is wear-resistant, and is suitable for high-strength applications.

Low Thermal Expansion Coefficient: Tungsten wire has small thermal expansion at high temperatures and good dimensional stability.

Oxidizability: In a high-temperature oxidizing environment, tungsten wire easily reacts with oxygen to form oxides, so it is often necessary to use it under vacuum or inert gas protection.
