This is a 2.39 mm tungsten cube, ground square and flat on every face. Each cube is cut from high density tungsten and finished with clean edges and a uniform surface, so it stacks, seats, and measures consistently.

Tungsten packs far more mass into a given volume than steel, brass, or even lead. That makes these cubes a favorite for precision counterweights, balancing and ballast, vibration damping, and as dense specimen cubes for collectors and classrooms.

Need a size, tolerance, or quantity you do not see here, or a certified industrial run? Those come straight from the source at Tungsten Parts Wyoming’s tungsten cube line, where pure and heavy-alloy grades are machined to print.

Frequently asked questions

What are 2.39 mm tungsten cubes used for?

They work as compact counterweights, balancing and ballast masses, desk-worthy density cubes, and test pieces where you want a lot of weight in a small, exact shape.

How dense is a tungsten cube compared to lead?

Tungsten is roughly seventy percent denser than lead, so a tungsten cube feels dramatically heavier than a lead piece of the same size.

Can I order a custom size or a large quantity?

Yes. Custom dimensions, tolerances, grades, and bulk runs are handled by Tungsten Parts Wyoming, the manufacturer behind these cubes.
