secondary metal matrix composite (MMC) powder with flake like particles of about 20 µm di ameter and 5 µm thickness was produced. After ball milling the secondary MMC powder was filled into aluminum capsules of 70 mm diameter, 2 mm wall thickness and about 220 mm height, and closed at one end with a circular plate of 5 mm thickness.
The produced flakes have a dimension of a thickness (t) < 0.5 µm and diameters (d) from 20 to 200 µm, consequently a ratio d/t up to 1000. The flake-geometry can be controlled by the variation of process parameters such as rotary speed of the rotor, ratio of powder/ball charge, filling ratio of the system, process temperature and operating model.

Method for the manufacturing of aluminum powder comprises dry grinding billet aluminum (aluminum powder obtained by atomization of liquid metal, waste aluminum foil, chips) in a very ball mill.
Aluminum powder is powdered aluminum. This was originally produced by mechanical means using a stamp mill to create flakes. The resulting powder might then be processed further in a ball mill to flatten it into flakes for use as a coating or pigment. Aluminum powder is non-toxic and is not harmful unless injected directly in a major blood ...
