Common Applications for Pure Tungsten

• Lighting. Tungsten has been used extensively as the filament in traditional incandescent light bulbs.  Due to low energy efficiency, high heat generation, and short service life, these light bulbs have been gradually replaced by fluorescent and lately by LED lights.
• Furnace parts and High-temperature alloys.  Due to high melting points and high strength, tungsten and its alloys are used in many high-temperature applications, such as arc-welding electrodes, heating elements and shields in high-temperature vacuum furnaces, and turbine blades in generators and aircraft engines.
• X-ray targets.  Tungsten is the most used target material in x-ray generation.  Tungsten has a high atomic number which increases the intensity of the x-rays at a set of voltage and current.  Its high melting point also allows the x-ray anode to become white-hot.
• Radiation shield.  Tungsten alloy combines the advantages of high density, high radiation absorption, high melting point and good corrosion resistance, is an ideal material to shield from various radiations.
• Armor penetrator.  The weapon uses the kinetic energy of a projectile to destroy enemy targets.  This energy is a function of the mass and its velocity when reaching the target (terminal velocity).  The mass is dependent on the density, and the terminal velocity is dependent on both the density and melting temperature.  Tungsten has both advantages.
