  • Manufacturing of aluminum flake powder from foil scrap

    2000-4-3 · The milling process of aluminum foil into the flake powder is shown systematically in Fig. 4, and the process is summarized as follows: (1) The foils is laminated, micro-forged by falling balls and elongated (Fig. 4b). (2) A crack occurs in the elongated foil and it is fragmented into small laminated pieces of foil or single piece of foil (Fig. 4c).
