The less reactive the milling fluid, the greater the tendency for particles to agglomerate by welding. Moisture in the powder promotes packing of large masses of powder in ball mills. Drying the powder at 100 °C (212 °F) or above often alleviates or eliminates this problem, especially with fine aluminum alloy powders. Brittle Fracture.

The manufacture of aluminum pigments involves a specialized ball-milling process as the first stage. Here the atomized aluminum is ball-milled in the presence of solvent and a lubricant for a period of five to 40 hours. The lubricant is employed to prevent "cold welding" of the aluminum particles and thus avoid agglomerates.

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 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.
