The particle-size distribution of Alcoa Aluminum Powders can be adjusted to produce a range of products from coarse to fine, and even superfine.

Coarse Powders
Alcoa Aluminum Powder coarse products are available with median particle sizes of 20 to 60 µm.  For details regarding typical particle size distributions and sieve analyses, please refer to our Coarse Powder Specifications.

Fine Powders
Fine aluminum powders in the 6 to 20 µm range are produced during the atomization process and separated in specially designed cyclone separators.  Our standard fine powders have median particle sizes of 6, 7, and 9 µm.  However, we consistently supply custom particle size distributions tailored to our customers' needs.  Details regarding the standard fine powders are included in our Fine Powder Specifications.

Superfine Powders
Superfine powders in the 3 to 6 µm range are produced by air classification.  We offer standard 4 and 5 µm products, but the particle size distributions of our superfine products can be tailored according to specific requirements for our customers. Details regarding the standard superfine powders are included in our Fine Powder Specifications.
