Magnalium used for strobe stars, for spark effects or to enhance other stars has to be finer than 120 mesh, while for use in crackling microstars it has to be something between 30 and 50 mesh. The coarser type is generally harder to find commercially. Magnalium can also be substituted into most mixtures that aluminum finds use in. These include; thermite and flash powder. Again, avoid unstable combinations, and remember that Mg/Al is very reactive.
Magnalium is much more powerful than aluminum powder (when compared at similar mesh size) and similar precautions should be taken as per magnesium. These include dangers of moisture and incompatibility with other compounds
Magnalium dust is harmful and a dust mask should be worn when handling fine dust. Mixtures containing nitrates or ammonium perchlorate and magnalium sometimes heat up and may ignite spontaneously, especially when moist. Coating with linseed oil will prevent reaction with nitrates, but this treatment does not protect the magnalium from ammonium perchlorate. Only treating with potassium dichromate will prevent this reaction. This is done by boiling in a 5% potassium dichromate solution. Adding fine potassium dichromate powder to such compositions may also help.
Awesome product!! exactly what I wanted. The Magnalium powder was nicely packaged in two plastic bags and very clean with no metal powder everywhere, I’m very impressed. The product exceeded my expectations, it’s really HOT! because of its fine particle size. I am so happy somebody is selling this because it is very hard to come across magnalium at this fine particle size, thank you for selling this amazing product. I plan to purchase more hopefully for years to come!

This stuff is amazing. Works great for strobe rockets and stars. I will be back for sure
Some of the best stuff I have ever used. Get it from here and you won’t be disappointed
Great stuff. Tested multiple sizes. Particle sizes are accurate and the material reacts perfectly.
Finally a solid source for Magnesium/Aluminum alloy. Nice stuff
