Tungsten carbide - Wikipedia
Tungsten carbide is approximately twice as stiff as steel, with a Young''s modulus of approximately 530–700 GPa (77,000 to 102,000 ksi), and is double the density of steel—nearly midway between that of lead and gold.It is comparable with corundum (α-Al2 O 3) in hardness and can only be polished and finished with abrasives of superior hardness such as cubic boron nitride and diamond powder
SiC Seal manufacturers - The Blogger''s Web
The relative density of sintered products can reach over 96%, and the products do not undergo excessive plastic deformation before and after firing. The fourth step: grinding drilling and milling, due to the high hardness of silicon carbide ceramics, the final cracking or cracking occurs in the grinding process, so choose artificial diamond grinding wheel.

It is also used in bulletproof vests as an armor material and as a seal ring material for pump shaft sealing where it frequently runs at high speed in contact with a similar silicon carbide seal. One of the major advantages in these appliions being the high thermal conductivity of Silicon Carbide which is able to dissipate the frictional heat generated at a rubbing interface.
