Fabrication of aluminum powder from foil scrap by a wet

2007-8-5 · Fabrication of aluminum flake powder by the wet ball milling of aluminum foil scraps and the effect of related factors were studied. As foil thickness decreases from 60 to 6.5 mm, mean size of powder milled for 30 h decreases from 107 to 17 mm. It is impossible to mill the foil without oleic acid to fabricate the flake powder.
