OSMIUM – precision density-standard cube 1cm3 – 22.6g NEW!
These are the most perfect and shiny Osmium cubes on the market! Ground and polished in our own facility in Vienna / Austria.
Osmium cubes require hot pressed (sintered) material rather than melted metal to avoid cracks and fissures at the grain boundaries. This must be carried out with great care and knowledge in order to prevent micropores on the surface that can release toxic OsO4 through oxidation reactions. Avoid Osmium cubes with mat and dull surface! Our cubes are tested and are safe!
The technically feasible maximum density is approx. 21g / cm3 which is compensated by adjusting the size by + 0.1mm.
Statements from other sellers like “full density” are always incorrect.
Production time about 2 weeks – Free laser engraving of your choice or standard engraving (in the picture you see a cube with standard engraving) Please note that this item is excluded from reductions or special offers.
We are leading manufacturer of metal density cubes of highest quality. Our cubes are famous for having perfect surface finish, sharp edges and exact size. Everything is made by master’s hand with love for details on our own workshop in Austria. We are often asked why our cubes cost about 3 – 5 times more than those from other sellers. Well…. you can buy a cheap car just for moving from one point to another – Or you fulfill your lifelong dream and buy the sports car you always wanted to have…
Using selected and high pure materials only, each density cube was lapped to 10x10x10mm to reach 1cm3 and 21.5×21.5×21.5mm (big 10cm3 cubes) in our lab with an accuracy of 0.01 millimeter. Each one separately ground and polished in a several hours lasting process. The cubes represent the theoretical density of the respective element by its weight.
