Tungsten Carbide is around twice as stiff as steel with a Young''s modulus of over 500 GPa and a low electrical resistivity of around 0.2 mW.m. In terms of hardness it is comparable to Sapphire or Ruby, ranking 9 on Mohs scale and requires cubic boron nitride or diamond tools and abrasives to be ground and polished into finished components.
A method for forming a polycrystalline ceramic fiber which comprises blending about 5 to about 25 weight percent polymer, about 70 to about 95 weight percent silicon carbide powder and greater than 1 weight percent sintering aid; forming a fiber from the blend; and
Tungsten carbide is approximately two times stiffer than steel, with a Young''s modulus of approximately 550 GPa, and is much denser than steel or titanium. It is comparable with corundum (α-Al 2 O 3 ) or sapphire/ruby in hardness and can only be polished and finished with abrasives of superior hardness such as cubic boron nitrideand diamond, in the form of powder, wheels, and compounds.
