0.5-inch Tungsten Cube (0.038kg)

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.

Each side measures 12.7mm, so this is a genuinely small object rather than a miniature-looking desk block. It can sit easily in a pocket or between your fingertips. Its size is what makes the weight interesting: a minimum of 37g is concentrated into a cube only half an inch across.

It is the most compact entry point in the range. Choose it if you want to experience tungsten’s density in something easy to carry and handle. If you want the weight to be more immediately dramatic, the larger sizes increase quickly in mass, starting with the one-inch cube at a minimum of 295g.
