Tungsten vs Tungsten Carbide – What's the Difference?
Tungsten already has a large elastic modulus, one larger than most steels; tungsten carbide has an even greater elastic modulus, showing its impressive rigidity. Generally, materials stiffness correlates with a large elastic modulus, and the values shown in Table 1 prove why tungsten carbide is second only to diamond in elastic resilience.
