  2. Tungsten - Wikipedia

    en.wikipedia.org/wiki/Tungsten

    Tungsten's hardness and high density make it suitable for military applications in penetrating projectiles. Tungsten compounds are often used as industrial catalysts. Its largest use is in tungsten carbide, a wear-resistant metal used in metalworking, mining, and construction. [22]

  3. Refractory metals - Wikipedia

    en.wikipedia.org/wiki/Refractory_metals

    The high melting point and the wear resistance against the electric arc makes tungsten a suitable material for the electrode. [21] [22] Tungsten's high density and strength are also key properties for its use in weapon projectiles, for example as an alternative to depleted Uranium for tank gun rounds. [23]

  4. Tungsten carbide - Wikipedia

    en.wikipedia.org/wiki/Tungsten_carbide

    Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through sintering [7] for use in industrial machinery, engineering facilities, [8] molding blocks, [9] cutting tools, chisels, abrasives, armor ...

  5. Tungsten steel - Wikipedia

    en.wikipedia.org/wiki/Tungsten_steel

    Tungsten steel is any steel that has tungsten as its alloying element with characteristics derived mostly from the presence of this element (as opposed to any other element in the alloy). Common alloys have between 2% and 18% tungsten by weight along with small amounts of molybdenum and vanadium which together create an alloy with exceptional ...

  6. Bulletproof vest - Wikipedia

    en.wikipedia.org/wiki/Bulletproof_vest

    The Improved Outer Tactical Vest (IOTV) in MultiCam, as issued to United States Army soldiers. A bulletproof vest, also known as a ballistic vest or bullet-resistant vest, is a type of body armour designed to absorb impact and prevent the penetration of firearm projectiles and explosion fragments to the torso.

  7. List of blade materials - Wikipedia

    en.wikipedia.org/wiki/List_of_blade_materials

    Chromium, molybdenum, vanadium, and tungsten are added for excellent sharpness and edge retention. Can be polished to an extremely high finish. Hardens and tempers to 60–62 HRC, where it best balances edge holding and toughness. Due to its alloying concept, this steel offers extremely high wear resistance and high corrosion resistance. [45]

  8. Cold saw - Wikipedia

    en.wikipedia.org/wiki/Cold_saw

    These blades are commonly used for cutting non-ferrous alloys, but have gained significant popularity for ferrous metal cutting applications in the last 10 years. The tungsten carbide inserts are extremely hard (98 HRC) and capable of very long wear life. However, they are less resistant to shock than solid HSS cold saw blades.

  9. Copper–tungsten - Wikipedia

    en.wikipedia.org/wiki/Copper–tungsten

    When the contact is very fine grained (VFG), the electrical conductivity is much higher than a normal piece of copper tungsten. [6] Copper tungsten is a good choice for a vacuum contact due to its low cost, resistance to arc erosion, good conductivity, and resistance to mechanical wear and contact welding.
