The hardness and yield strength of powder particles were improved by ball milling, so the relative density of milled powder compact was lower than nonmilled compact. Therefore, the sintering density of milled samples is lower. The density of nonmilled and milled samples is ± and ± % after extrusion.

Intermediate stops during the ball milling can provide finer aluminum flake powder for up to 25 h due to cooling of the vial. A larger amount of stearic acid reduces friction between the powder or the balls and vial wall,thus decreasing mill efficiency,and 3wt% stearic acid additive is verified as the optimum content. Thus produed aluminum ...

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 μm, mean size of powder milled for 30 h decreases from 107 to 17 μm. It is impossible to mill the foil without oleic acid to fabricate the flake powder.

The pigment particles are conventionally manufactured by wet or dry milling in ball mills from melt atomized metal powder, which only results in flat particle geometries [4]. Depending on the particle size, aluminum powder is pyrophorous [5,6], which is why aluminum pigments are usually milled in wet conditions [3].
