Tungsten wire

Tungsten wire is a filament made of tungsten (chemical element symbol W) that generally has excellent physical properties and is particularly suitable for applications with high temperature, high strength and high corrosion resistance. The following is a brief introduction to tungsten wire:

1. Physical properties: Tungsten is a high melting point metal with a melting point of approximately 3422 degrees Celsius (6192 degrees Fahrenheit) and is one of the elements with the highest melting point in nature. This allows the tungsten wire to maintain its structure and performance under extreme high temperature conditions.

2. High strength: Tungsten wire has excellent strength and hardness, and can maintain its mechanical properties even at high temperatures. This makes it useful in high-temperature heaters, arc welding electrodes, and other high-temperature applications.

3. Electrical conductivity: Although tungsten is a metal, its electrical conductivity is relatively low. Therefore, when tungsten wire is used as a conductive wire in electronic devices, it is usually doped or alloyed to improve its conductivity.

4. Corrosion resistance: Tungsten has good corrosion resistance and is relatively stable to many chemicals, which makes it of certain application value in the chemical industry and high-temperature corrosive environments.

5. Application fields: Tungsten wire is widely used in many fields, including electronics, aerospace, chemical industry, medical equipment and nuclear energy. In the field of electronics, tungsten wire is commonly used in electron tubes, semiconductor manufacturing, high-temperature resistors and hot wires in vacuum technology. In the aerospace industry, tungsten wire is used to manufacture rocket nozzles and high-temperature engine components due to its high melting point and high temperature resistance. Additionally, tungsten wire is used in medical equipment to make X-ray tubes.

In summary, tungsten wire is a versatile material that is widely used in multiple industrial and scientific fields due to its excellent high temperature properties and corrosion resistance.
