Tungsten Carbide Introduction

Tungsten Carbide is neither a metal nor is it a ceramic. It is a cermetal although this isn't a widely used term. This is a combination of a large percentage of Tungsten Carbide ceramic particles bonded together by a small percentage of a metallic binder, to form a solid mass.

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 ball-sizing and they provide premier results as components of kinematic couplings.
