Buying guide
How much does a tungsten cube cost?
Ours run from $89 for the 1-inch to $1,299 for the 3-inch. Across the wider market you will see roughly the same shape: double-digit prices for small cubes, and a steep climb from there.
The climb is steep because cost tracks mass, and mass scales with the cube of the edge length. A 2-inch cube contains eight times the tungsten of a 1-inch cube, not twice.
What you are actually paying for
Roughly half of a tungsten cube's price is raw material and roughly half is machining, and the ratio shifts toward machining as the finish quality goes up.
Tungsten is difficult to cut. Its hardness and its 3,422°C melting point mean the feeds and speeds that work on steel destroy standard carbide tooling, so producing flat faces, square corners and a consistent surface finish takes slow, deliberate work on equipment set up for it.
That is why two cubes of identical size and stated purity can differ in price by a factor of two. The cheap one usually has rounded edges, visible tool chatter, or faces that are not quite parallel.
What to check before buying
Purity. 99.95% is the standard for a good cube. Anything that does not state a figure is usually a tungsten alloy or a heavy-metal sinter, which is denser than steel but noticeably lighter than pure tungsten.
Stated weight against the physics. Multiply the edge length in centimetres, cubed, by 19.3. If a seller's stated weight is meaningfully below that number, the cube is not solid pure tungsten.
Finish and edge quality, which are what you actually look at every day, and the main thing separating a desk object from a lump of metal.
Why prices vary so much between sellers
Tungsten is a commodity with a volatile spot price, and most sellers buy machined cubes rather than machining them. That means you are often comparing the same few factories at different margins.
The differences that are real: purity, tolerance, surface finish, and whether anyone inspected the cube before it shipped.
Common questions
How much does a tungsten cube cost?
Ours run from $89 for the 1-inch to $1,299 for the 3-inch. Prices scale steeply with size because mass scales with the cube of the edge length, so a 2-inch cube contains eight times the tungsten of a 1-inch one.
Why are tungsten cubes so expensive?
Material cost plus machining difficulty, roughly half each. Tungsten's hardness and 3,422°C melting point require specialised tooling and slow feed rates to produce flat, square faces with a clean finish.
Are cheap tungsten cubes worth buying?
Sometimes, but check the stated weight against the physics: edge length in centimetres, cubed, times 19.3. A cube meaningfully lighter than that figure is an alloy or a sinter, not solid pure tungsten.
