Aluminium powder
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. Aluminium powder, if breathed in, is not particularly harmful and will only cause minor irritation. The melting point of aluminium powder is 660 °C.Usage
Depending on the usage, the powder is either coated or uncoated.
