Tungsten Sheet Plate ASTM B760 W Sheet

Tungsten is a greyish-white lustrous metal; it is solid at room temperature. It has the highest melting point, lowest vapor pressure at temperatures above 1650 °C, the highest strength, and the highest hardness among all pure metals and alloys. Pure tungsten metal was first isolated by two Spanish (de Elhujar) brothers in 1783. The word “tungsten” comes from a Swedish “tung sten”, meaning “heavy stone.” Tungsten’s chemical symbol “W” comes from the element’s other name, wolfram, which is derived from wolframite, the mineral the element was discovered in.
  • Description
  • Material: Purity 99.95% Min.

    Specification: ASTM B760

    Tungsten Sheet Plate Properties:

    • High Density: 19.25 g/cm³  High Melting Point: 3422°C (6192 °F)
    • Low Vapor Pressure  High Tensile Strength  High Ductility
    • Low Coefficient of Thermal Expansion
    • High Thermal and Electrical Conductivity
    • Good Machinability   High Corrosion Resistance   High Elastic Modulus

    Application:

     ∗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.
