WSM Posted August 1, 2010 Share Posted August 1, 2010 That never took Chemistry, what size in microns is this d50=3.21um,ALUMINUM POWDER Thanks Hi Algenco, It looks like it says 3.21 microns. If that's so, it's very fine and would make very short-tailed glitter (or very hot flash, not that we ever do such things) or could be used in AP rocket fuel, or used to speed up certain color star compositions. Do you have a lot of it or just a sample? WSM Link to comment Share on other sites More sharing options...

WSM Thanks for the answer, I found it on Ebay, 20 lb for $160.Doesn't look like something I need, I don't care much for loud noises http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=190345763377&ssPageName=STRK:MEWAX:IT Edited August 1, 2010 by Algenco Link to comment Share on other sites More sharing options...

If the listed aluminum is free of grease or diluents it would be great for flitter stars, niagra falls sticks, glitter stars or other types of such fireworks. What kind of aluminum are you looking for (what are you hoping to make)? WSM Edited August 1, 2010 by WSM Link to comment Share on other sites More sharing options...

WSM Posted August 1, 2010 Share Posted August 1, 2010 Something for star/comets/etc for glitterJust looking for cheaper source I'd be sure it's NOT paste, but dry aluminum powder. Paint suppliers use a greasy paste for mixing with carriers to make aluminum paint. The grease would have to be cleaned off first if you want it for use in pyrotechnics. I'd pass if it's not dry flitters (stearine [stearic acid] added is okay). WSM Link to comment Share on other sites More sharing options...

Good luck with that! It would be cool to have a variety of material shapes and sizes available in less than industrial quantities. WSM Link to comment Share on other sites More sharing options...
Twotails Posted August 2, 2010 Share Posted August 2, 2010 If your looking for some good Al for glitter and such, Underground gadgets has(or had) some nice spherical -325 mesh Al. I think I picked up 5lbs for like $20-30 bucks. Link to comment Share on other sites More sharing options...
