Silicon Nitride Balls

Tooling Fixture and Checking Balls
Tungsten Carbide and hardened Stainless Steel Balls are widely used to provide locations and position reference for both manufacturing tooling and for metrology. Tungsten carbide has the advantage of high hardness 1500 - 1600 Hv, and a low coefficient of expansion.

Stainless Steel offers the same dimensional accuracy, and has a coefficient of expansion which matches most steels. It does require greater care in handling, but is preferred in some metrology and fixturing applications.
