Aluminum Powder 101 Production of aluminum powder. Aluminum powder was originally produced by using a stamp mill to create flakes. In the 1920s, E. J. Hall pioneered the process of spraying molten aluminum to make powder droplets. Today, molten aluminum is sprayed under high pressure to produce a fine granular powder.
