Aluminum powder is powdered aluminum. This was originally produced by mechanical means using a stamp mill to create flakes. Subsequently, a process of spraying molten aluminum 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. Aluminum powder, if breathed in, is not particularly harmful and will only cause minor irritation. The melting point of aluminum powder is 660 °C.
- cosmetic colorant
- in paints as metallic silver pigment
- Fingerprint powder
- Rocket and missile fuel
- production of Autoclave aerated concrete.
Depending on the usage, the powder is either coated or uncoated.
