Fabrication of aluminum flake powder from foil scrap by a wet …
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.

Decorative and Functional Metallic Effect Pigments
Figure 4 displays the impact of particle size and shape on the brilliance of aluminum pigments prepared by wet milling. The irregular flake geometries of cornflake grades (Figure 3a) are characterized by lower surface-to-edge ratio and much higher surface roughness (Figure 4). Light scattering occurs at the edges, resulting in lower …

Chemical etching of aluminium
The first chemical etchings of aluminium were mainly carried out for decorative purposes. Chemical etching of aluminium was industrially completed by M.C. Sanz from North Aviation Inc. in 1956; he took the US patent (Patent no.: 2,739,047) and named the process "chemical milling" or in short "chem-mill" (Sanz, 1956).
