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
