Homemade Black Aluminum
Check out this video, I found it interesting, I never realized it had to be ball milled for so long. Some people will do anything to save $20.00 for a pound of pyro Aluminum. LOL

$20 for a pound of German Blackhead Aluminum powder? Wow, that's overpriced. I bought 9 pounds of it from Ebay for exactly $144.:cool:
Here are some pictures of my order:

At about 3:45 did he say steel oxides ? I thought oxides such as iron and lead reacted with aluminum powder ? I heard of people having problems ball milling aluminum or magnesium for that matter because of contamination. Fires and blowing the lid off the container. I say buy it if you want it.

If I were you, I wouldn't ball mill Aluminum for the flash powder. I would only ball mill the Potassium Perchlorate. That Aluminum can get very very dangerous most of the time. Be careful with it lol.
