This is a precision tungsten ball turned to a 63.5 mm (2.5 inch) diameter. It is machined from high density tungsten and polished for consistent rolling, seating, and weight.

Tungsten is far denser than lead or steel, so even a small piece carries surprising heft. Tungsten balls this dense are used for counterweights and trim weights, flow and check valves, inertia and vibration control, and demanding ballast work.

For a diameter, tolerance, or grade beyond this listing, or a certified production quantity, go to custom tungsten spheres and balls and the manufacturer will machine it to your spec.

Frequently asked questions

What is a 63.5 mm (2.5 inch) tungsten ball used for?

Common uses include high-density counterweights, valve and flow components, inertial and vibration control, and ballast where space is tight but weight matters.

Why choose tungsten over a steel ball?

Tungsten carries far more mass for the same diameter, so you get the weight you need without going to a larger ball.

Do you offer other diameters or certified batches?

Yes. Additional sizes, tolerances, and certified production runs come from Tungsten Parts Wyoming, the manufacturer.
