Aluminum pigments are manufactured using a ball mill process in which high purity aluminum is combined with a solvent and lubricant to facilitate the particle size reduction of the alloy. After hours of processing the solventborne aluminum flakes are collected, screened and passed through a press to remove most of the solvent.
The aluminum forms small balls or spheroids. Spherical aluminum is available in many sizes, from -400 to -20 mesh. ¥ Flake aluminum is made in a number of different ways. It can be made by ball milling or stamping. Stamped aluminum is made by placing aluminum in a hard mortar, and using a mortar to stamp it flatter and flatter.

In the case of the industrial scale developed Aluminum-based nanocomposites, we have followed similar experimental conditions to those previously discussed in Section 2.1 for the homogeneous dispersion of the carbon nanotubes into metallic powders, but instead of using the planetary ball-mill equipment (Retsch, PM 100), now a high material ...
Two major breakthroughs developed by Hall (Ref 4) occurred in aluminum powder production in the late 1920s. First, the development of safer ball mill production processes that are still employed today for milling powders into flakes. Second, the introduction of the atomization process, which allowed the manufacture of the forerunners of today's ...

This powder, known as 'aluminium bronze', is a flaky powder with a stearin coating. It is quite expensive but readily available and a source for small quantities. Aluminium grit and turnings can sometimes be found in machine shops were aluminium is processed. If fine enough this can be used as is, but it can also be ball milled into flakes.
