Finding Hardness values

  1. Nov 4, 2009 #1
    Is there a website or book that lists hardness values for the following:

    Polycrystalline Boron Nitride
    Molybdenum
    Tungsten Carbide
    Diamond
    h13
    B4C
    SiC
    Al2O3

    I've tried www.matweb.com, but they only have hardness values for some of these materials. I can't locate PCBN in their database either.

    Thanks for any help!

    You could try the Handbook of Refractory Carbides and Nitrides. They quote a Vickers hardness of 0.08-0.09 GPa for "hot-pressed boron nitride."
