Thin tungsten wire refers to a thin wire made of tungsten, usually with a diameter of less than 0.5mm. Tungsten is a metal with high density, high melting point, and high hardness, so thin tungsten metal wire has extremely high heat resistance, corrosion resistance, and wear resistance. They are widely used in high-temperature heating, arc welding, electronic devices, filaments, vacuum melting, and other fields.
1. Feature
Very high melting point and thermal stability can operate at high temperatures.
Very thin, usually between a few microns and a few millimeters in diameter.
It has excellent corrosion resistance and can be used in acidic, alkaline, and high vacuum environments.
1) Physical properties
High density, tough and durable.
It has good ductility and plasticity and can be easily processed into various shapes.
Has good electrical and thermal conductivity.
2) Chemical properties
It is not easy to be chemically corroded at room temperature. However, at high temperatures, it will be subjected to chemical reactions such as oxidation and nitrification, resulting in a reduction in wire diameter or fusing.
It has good stability in the environment of hydrogen, nitrogen, argon, and other inert gases.
In conclusion, thin tungsten wire is a very good high-temperature and corrosion-resistant material, widely used in semiconductors, optics, aerospace and other fields.
2. Manufacture Processes
The basic process of producing thin tungsten wire is as follows:
1) Purchasing raw materials: Purchasing high-purity tungsten blocks as raw materials usually requires chemical analysis to ensure that its purity meets production requirements.
2) Tungsten block processing: Put the purchased tungsten block into the furnace for heating, make it melt and become a rod of a certain shape (such as round rod, flat rod, etc.), and then stretch and deform the tungsten rod to form the corresponding tungsten rod. Silk.
3) The shape of the wire: the stretched tungsten wire is cut off, and then heat-treated or roasted to adjust its physical and chemical properties.
4) Quality inspection: inspect the finished product, and customize the diameter, length, surface treatment, etc. of the wire according to the requirements, and finally pack it.
The above is the basic production process of thin tungsten metal wire. According to different production requirements and supplier requirements, there are still some detailed processes that need to be adjusted.
Thin tungsten wire is a very tough metal wire that is gaining popularity in different fields of application due to its high melting point and high strength. The following is the working principle and application fields of tungsten wire:
Working principle: The main working principle of thin tungsten metal wire is to increase its surface temperature through resistance heating, thus realizing its various applications.
3. Application fields
1) Thermocouple: It is high stability and high-temperature resistance make it an ideal material for thermocouples, used in thermometers and thermocouples.
2) Light-emitting diodes (LEDs): It is used as a current-carrying wire to drive the chip to emit light, making the LED more efficient.
3) Vacuum melting: It is high melting point and high stability make it an ideal material for manufacturing vacuum melting devices such as tungsten filaments, filaments, discharge tubes, valves, and nozzles.
4) Electronic electrodes: It can be used as electrode materials for electronic devices, such as cathodes and anodes.
5) Textiles: It can also be used to make textiles, such as simulated spider wire.
In summary, due to its high strength and high melting point, thin tungsten wire can be used in many fields, from electronics to gas heating, as well as medical equipment manufacturing, and even process manufacturing, there are a large number of applications.
