Milling aluminum without good techniques is a GREAT way to get seriously hurt and make a useless product. See, aluminum is very ductile, and when you smash two tiny bits together between anvils (hard media) they will squish together into a LARGER particle. I think I read the smallest you'll get from ball milling Al is about 200-250 mesh.
Effect of ball milling (BM) of an aluminum powder on hydrogen generation through a reaction with hot water was investigated. BM increased surface area of the aluminum particles, increased crystalline imperfections in the aluminum lattice, and removed a native oxide film on surface of the particles. The increase in surface area of the particles was studied by …

Aluminium powder is powdered aluminium.This was originally produced by mechanical means using a stamp mill to create flakes.Subsequently, a process of spraying molten aluminium to create a powder of droplets was developed by e.J.Hall in the 1920s.The resulting powder might then be processed further in a ball mill to flatten it into flakes for use as a coating or pigment.
can we mix aluminium and alumina nano powders in ball milling. Sep, the xrd patterns of the ball milled al alloy and algnss powder mixtures at different milling times are shown in figs and respectively, revealing the microstructural evolution of the powder mixing during the ball milling it is seen that the peak intensity of aluminium decreases with the increase of milling times up to h

3.2. Methods and procedures. A stainless steel bowl was loaded with 200 g Al and 4 vol.% of Al 2 O 3 powders with a ball-to-powder weight ratio of 5:1; meanwhile, to identify the effect of the nanoscale Al 2 O 3 reinforcements on the ball-milled composite powders, 200 g of Al without Al 2 O 3 was loaded into another stainless steel bowl. To prevent excessive cold …
I am working on ball milling of Aluminum powders for a couple of years and a question yet not answered to me is that "why sometimes- not always or so many- I …
Sanding aluminum chunks can also make aluminum powder. Ive heard of people building a machine to do this and the results can be quite good depending on the sandi ng paper used and the set-up. Another source of usable aluminum powder is to burn tetra-paks and then powder the resultant aluminum residue in a ball mill. Details

At the same time, the powder particle size is not especially crucial. If it should be smaller than the grinding ball size, the powder particle size decreases exponentially with time and reaches a small value after a few minutes of milling. These powders include many kinds of pure metals, master alloys, prealloyed powders and refractory compounds.
Pure aluminum alloy (AA7075) powder (about 46 µm in size) and nano-Y 2 O 3 powder (99.9% purity, 35 nm in size) were used to produce Al-based metal matrix composites. AA7075 was employed as the matrix material, and its chemical composition is given in Table 1.The matrix material was reinforced with 0.5 wt% nano-sized Y 2 O 3.Considering the …
