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.
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 it represents the theoretical density of the respective element by its weight.
