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?

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

Wow, I jumped the gun. 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)?

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).

Thanks,

I have several grades, enough to do me for awhile, just looking

 

Eckart America isn't far from me, maybe I can find an employee that can around their minimums.

Good luck with that! It would be cool to have a variety of material shapes and sizes available in less than industrial quantities.

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.
