What is a Tungsten?

Tungsten, represented by the chemical symbol "W" and atomic number 74, is a chemical element known for its extremely high melting point (approximately 3422°C) and high density. Due to these properties, it is widely used in heavy industry and high-temperature environments. Tungsten is an essential alloying element in steel, particularly in tool steels and heat-resistant alloys. It is also used in the production of light bulb filaments, vacuum tubes, radiation shielding, and electrical contacts. In aerospace and space exploration, tungsten alloys are utilized for components subjected to high temperatures and harsh conditions. Additionally, tungsten exhibits excellent wear resistance and resistance to corrosion, making it ideal for use in chemical equipment, cutting tools, and drill bits in high-stress environments. However, its processing requires advanced technology, and its cost is relatively high, limiting its applications to specific uses.

Application of Tungsten

１．Light Bulb Filaments: Tungsten is widely used in light bulb filaments due to its high melting point, allowing the filament to withstand high temperatures without melting.
２．Aerospace Industry: In the aerospace sector, tungsten alloys are used in components such as rocket nozzles and heat shields, as they can withstand extreme temperatures and stress.
３．Electrical Contacts: Tungsten is used in electrical contacts and relays because of its excellent conductivity and durability under high temperatures and high electrical loads.
４．Cutting Tools: Tungsten carbide, a compound of tungsten, is commonly used in cutting tools, drills, and machining tools due to its hardness and resistance to wear.
５．Radiation Shielding: Tungsten is used in radiation shielding for medical equipment and industrial applications because of its high density, which effectively absorbs and blocks radiation.
