These are 10.00 mm (0.393 inch) solid tungsten balls, machined round and dense for use as high-mass shot, ballast, or precision weights.

Tungsten packs far more mass into a given diameter than steel or lead, so these balls deliver serious weight in a compact sphere.

For other diameters, tolerances, or certified quantities, Tungsten Parts Wyoming machines tungsten balls to spec.

Frequently asked questions

What are the 10.00 mm (0.393 inch) tungsten balls for?

They serve as high-density shot, counterweights, and ballast where you need maximum weight in a small round form.

How dense are they?

Tungsten is far denser than steel or lead, so a tungsten ball far outweighs a same-size ball in those metals.

Can I get other sizes?

Yes. Additional diameters and certified runs come from Tungsten Parts Wyoming, the manufacturer.
