This is a solid tungsten ball measured at 12.7 mm (.50 inch) across. It is machined from high density tungsten and polished for consistent rolling, seating, and weight.

The high density of tungsten makes it ideal wherever you need maximum weight in a minimum footprint. 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 12.7 mm (.50 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.
