Ball milling magnesium Page 2 Safety APC Forum

Jan 28, 2015 · Page 2 of 2 Ball milling magnesium posted in Safety: Aluminum is probably a little safer than magnesium but still very dangerous. When metals are milled they are broken down and fresh metal is exposed and the protective layer of oxide is broken down. When the powder is exposed to air the oxygen starts to oxidize the metal which is an exothermic process and releases heat.

Magnalium Wikipedia

Magnalium powder also burns with a crackling sound if burnt by itself, and provides a good compromise between the reactivity of magnesium, and the stability of aluminium. Another benefit for pyrotechnics is the brittleness of the alloy, as mentioned before. It is easily broken with a hammer and then ground in a coffee grinder to usable powder.
