Cemented Tungsten Carbide is extremely stiff, with a Young's modulus of elasticity of 98,000,000 pounds per square inch, compared with steel at 30,000,000 PSI. This high stiffness makes cemented tungsten carbide balls a good choice for ballsizing and they provide premier results as components of kinematic couplings.
