Aluminum Powder -40+325 Mesh 99.8%
Aluminum powder is powdered aluminum. This was originally produced by mechanical means using a stamp mill to create flakes. 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 is non-toxic and is not harmful unless injected directly in a major blood vessel such as the aorta. Aluminum powder, if breathed in, is not particularly harmful and will only cause minor irritation. The melting point of aluminum powder is 660 °C.
