Tungsten Coil

Tungsten coils are high-performance coil products that are applied in a wide range of industries. These are manufactured from pure tungsten; some properties include high heat resistance, high melting point and good electrical conductivity. Since tungsten coils have high resistance to temperature and possess high mechanical strength, they are used in applications where high durability and precision are required, for instance, in high-intensity discharge lamps, vacuum tubes and electron microscopes. 

Features of Tungsten Coil

Tungsten coils offer several notable features that make them valuable in various high-performance applications:

• High Melting Point: Tungsten coils are characterised by a very high melting point and hence are suitable for use in high temperature applications. 
• Excellent Electrical Conductivity: Tungsten Coils have higher electrical conductivity as compared to the other materials which are important for those applications that require high electrical performance. 
• Outstanding Thermal Conductivity: Tungsten coils are good conductors of heat and this is useful in the areas of heat control. 
• Superior Strength and Durability: Tungsten coil’s inherent strength absorbs mechanical stress well, which means that coils are not deformed or fail under heavy usage. 
• Resistance to Corrosion: Tungsten coils can withstand oxidation and corrosion at high temperatures, thus improving their durability and efficiency. 
• Low Vapor Pressure: Tungsten has low vapour pressure and as such it can be used in high vacuum conditions and other applications in high energy electron or ion beams. 
• Thermal Stability: Tungsten coils do not undergo any significant metallurgical changes at high temperatures and thus can be used in applications that require high temperature performance. 
• High Density: Tungsten has a high density and this makes it strong and reliable in many uses and particularly where high force impacts are involved. 

Tungsten coils are ideal for applications that require high reliability and performance since they possess superior characteristics. 

Applications of Tungsten Coil

Tungsten coils are applied in a number of high-stress uses because of their special characteristics. Some key applications include: 

• High-Intensity Discharge (HID) Lamps: In HID lamps, the tungsten coils act as the filament or the electrode and are used in metal halide and mercury vapour lamps. 
• Electron Microscopes: Tungsten coils are used as electron emitters in electron microscopes and are useful in producing beam electrons in high vacuum conditions. 
• Vacuum Tubes: Tungsten coils are used as essential parts of vacuum tubes such as the cathode-ray tubes and radio frequency tubes. 
• Gas Discharge Tubes: In gas discharge tubes and fluorescent lighting, tungsten coils are utilized as electrodes that help in the discharge of the gas through the provision of heat and electrical conductivity. 
• Welding: In tungsten inert gas (TIG) welding, tungsten coils are used as electrodes because of the good stability of the arc and the ability to avoid wear during welding. 
• Spacecraft and Aerospace Components: Tungsten coils have been used in aerospace applications, including propulsion systems, structural materials, avionics and thermal protection systems. 
• Heat Lamps: In industrial and medical heat lamps, tungsten coils are used because they give out consistent heat and are very intense, thanks to their high melting point and thermal stability. 
• High-Temperature Furnace Elements: Tungsten coils are heating elements in high-temperature furnaces and ovens. 

Tungsten coils are vital in use in areas where high performance is required under extreme conditions.
