Tungsten Wire Description
Tungsten is one of several materials commonly used to make electron emitters. The advantage of tungsten is its extremely low vapor pressure even at high temperatures. Tungsten has the highest melting point of all the metallic elements and a density comparable to that of uranium or gold and about 1.7 times that of lead.Tungsten Wire (W Wire) is widely used in lighting, electron tubes, electrodes, high-temperature furnace parts, and probe pins thanks to its excellent properties like the highest melting point among metals, etc.
Tungsten Wire Application
1. Lighting Industry: Used in incandescent light bulbs and halogen lamps as filaments due to its high melting point and resistance to heat, enabling the production of bright and long-lasting illumination.2. Electronics: Employed in electronics manufacturing for wire bonding applications in semiconductor devices, integrated circuits (ICs), and electronic components, where high conductivity and stability are crucial.
3. Heating Elements: Utilized in high-temperature heating elements for industrial furnaces, vacuum furnaces, and heating applications in laboratories, where tungsten's high melting point and oxidation resistance are advantageous.
4. Vacuum Metallurgy: Applied in vacuum metallurgy processes such as electron beam welding, electron beam melting, and vacuum evaporation for depositing thin films and coatings, where tungsten's low vapor pressure and high melting point are essential.
5. Medical Devices: Utilized in medical imaging and diagnostic equipment such as X-ray tubes and CT scanners as anode filaments due to its high atomic number, which enables efficient X-ray production.
6. Aerospace and Defense: Employed in aerospace and defense applications such as missile guidance systems, aircraft countermeasures, and electronic warfare equipment due to its high strength, density, and resistance to high temperatures.
