3-Inch Tungsten Cube (8kg)

Choose by the physical experience you want. The smaller cubes make tungsten’s density surprising because so much weight is concentrated into so little space; the larger cubes turn that same property into a much more substantial object. Compare the dimensions and minimum weights carefully before ordering, particularly from 2 inches upwards.

The cube is solid high-density tungsten alloy rather than a hollow or tungsten-coated object. Project Atomic cubes use a tungsten alloy that is 95% to 97% tungsten, depending on material availability. The small amount of nickel with iron or copper allows the material to be manufactured into a precise finished cube.

Tungsten content can vary between 95% and 97% depending on material availability, which changes density slightly. Manufacturing tolerances can also produce small variations between individual cubes. Where a product is sold with a minimum weight, that minimum is the figure to use when comparing it with another size.

Handle it with clean, dry hands and wipe the surface with a soft cloth when needed. The more important consideration is its mass: larger tungsten cubes can damage desks, shelves, floors or other objects if dropped. Use the supplied packaging or stand where appropriate and take particular care when moving the heavier sizes.

The Imperfect option is the same 2-inch tungsten cube with minor surface imperfections. It has the same material, dimensions and minimum weight; the difference is cosmetic. It is an option for someone who wants the physical experience of the cube and is less concerned about an immaculate display finish.

Its minimum weight is 8kg, so think about where it will live as well as how it will be handled. The cube occupies only 76.2mm per side, which can make the mass easy to underestimate visually. Choose a suitable surface and take care whenever lifting, carrying or repositioning it.

The move from a minimum of 4.6kg to a minimum of 8kg is substantial. Both are compact display objects, but the three-inch version requires much more deliberate handling. It is less about occasionally picking up a dense curiosity and more about experiencing just how much mass tungsten can concentrate into a small volume.
