Aluminium powder
Aluminium pigment powder
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. Aluminium powder is non toxic and is not harmful unless injected directly in a major blood vessel such as the aorta. Aluminum powder, if breathed in, it is not particularly harmful and will only cause minor irritation.[1] Melting point: 660 °C
