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!
