    If Meyer's index is greater than 2.2, then the ratio increases. [ 1 ] The Brinell hardness is designated by the most commonly used test standards (ASTM E10-14 [ 2 ] and ISO 6506–1:2005) as HBW ( H from hardness, B from brinell and W from the material of the indenter, tungsten (wolfram) carbide).

    Elastic properties describe the reversible deformation (elastic response) of a material to an applied stress.They are a subset of the material properties that provide a quantitative description of the characteristics of a material, like its strength.

  5. Lead - Wikipedia

    en.wikipedia.org/wiki/Lead

    Lead played a crucial role in the development of the printing press, as movable type could be relatively easily cast from lead alloys. [9] In 2014, the annual global production of lead was about ten million tonnes, over half of which was from recycling. Lead's high density, low melting point, ductility and relative inertness to oxidation make ...
