Mg+Al powder as magnalium substitute? posted in Pyrotechnic Formula: Hey, i was wondering if i could just mix magnesium powder and aluminum powder together and use that as magnalium. Im not new to the pyroworld, just new to inorganic stars and dragons eggs. I have everything to make the dragons eggs, using Pb3o4 (i have a gasmask, gloves and goggles, don't worry) i just don't have the magnalium.

Likely, you will need to ball mill your magnalium though. You can try using the mesh you currently have, but you do want a fast strobe reaction, so getting that magnalium down to size is a good idea. 1percent copper oxide can be mixed in as well to speed up the strobe reaction if you have probs.

Now, ball milling Mg/Al can be dangerous. Let me just put that out there to start with. The trick is, determining how long you can mill it before it becomes dangerously fine. I would suggest milling in stages, for an hour or two at a time, until it is as fine as you want it. STOP when the powder goes from looking silver to more of a dull grey ...

Composition Magnalium consists of aluminium and magnesium in different ratio. The common alloy used for bulk materials consists of 95% Al and 5% Mg by weight. The alloy used in pyrotechnic mixtures consists of 50% Al and 50% Mg, which is why this alloy is sometimes wrote as AlMg 50:50 . Properties
