  4. Tungsten - Wikipedia

    en.wikipedia.org/wiki/Tungsten

    About 50% of tungsten is used in tungsten carbide, with the remaining major use being alloys and steels: less than 10% is used other compounds. [ 21 ] Tungsten is the only metal in the third transition series that is known to occur in biomolecules , being found in a few species of bacteria and archaea .

  5. 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 facility,mold industry,cutting tools, chisels, abrasives, armor-piercing ...

    Tungsten, for example, still made the list in both metallic and carbide forms. Diamond, graphite, boron nitride joined that list, as did transition metals like molybdenum, tantalum, and rhenium.

  7. Tantalum–tungsten alloys - Wikipedia

    en.wikipedia.org/wiki/Tantalum–tungsten_alloys

    The tantalum–tungsten alloys typically vary in their percentage of tungsten. Some common variants are: (Ta – 2.5% W) → also called 'tantaloy 63 metal.' The percentage of tungsten is about 2 to 3% and includes 0.5% of niobium. This alloy has a good resistance to corrosion and performs well at high temperatures.

  8. High-speed steel - Wikipedia

    en.wikipedia.org/wiki/High-speed_steel

    Generally, the X component is present in excess of 7%, along with more than 0.60% carbon. In the unified numbering system (UNS), tungsten-type grades (e.g. T1, T15) are assigned numbers in the T120xx series, while molybdenum (e.g. M2, M48) and intermediate types are T113xx. ASTM standards recognize 7 tungsten types and 17 molybdenum types. [11]

  9. Reactivity series - Wikipedia

    en.wikipedia.org/wiki/Reactivity_series

    Standard electrode potentials offer a quantitative measure of the power of a reducing agent, rather than the qualitative considerations of other reactive series. However, they are only valid for standard conditions: in particular, they only apply to reactions in aqueous solution. Even with this proviso, the electrode potentials of lithium and ...
