Cherbanov Posted October 5, 2006 Posted October 5, 2006 I got Aluminium bars and stick, I have made some fillings of it. 1: can i use this in anyting, maby in stars? 2: can i ball mill it to make it smaller ore to a powder?
Mephistos Minion Posted October 5, 2006 Posted October 5, 2006 Your powder will be OK in stars, you should be able to use is where ~20 mesh granular/flitters are called for. It will be good for waterfalls.
Cherbanov Posted October 5, 2006 Author Posted October 5, 2006 ok thanks fore the help, i will try to get some nice stars with it then.
itwasntme Posted October 5, 2006 Posted October 5, 2006 Be carful when ball milling it as it can become pyrophoric(ignite when exposed to air). You can add it a rocket to make a tail. Not sure but maybe put it in a shell with some stars, it might come back to earth though.PS: nice camera!
XenoN Posted October 5, 2006 Posted October 5, 2006 I used a powder a little larger than this for very cheaply made fountains. I also ball milled some to make a nice fine powder.
aquaman Posted October 5, 2006 Posted October 5, 2006 If you want to make it finer try milling some of the Al with some coins, like quarters and nickels for about a couple of days. It will become finer but very slowly. Also for an alumminum effect you can use aluminum foil but I think your aluminum bars will be better. If you do choose to mill some open the mill up every now and then (24hrs) to let fresh air in. BTW you might want to resize that picture... Use this URL "http://img247.imageshack.us/img247/3003/post41160017547kn7.jpg" or something like that so the forum reads ok. http://img247.imageshack.us/img247/3003/post41160017547kn7.jpg
Cherbanov Posted October 6, 2006 Author Posted October 6, 2006 the camera is a Canon EOS 350D with 8mega pixels, I will resize them even more next time. the link dosent work for me. witch size would be god fore this forum original size is 3456*2304. can I use stell balls to make the al powder? ore has it to be something with rought edges.
h0lx Posted October 6, 2006 Posted October 6, 2006 that image shouldn't need more than 640x480 ins size, which also doesen't stretch the forum...
Polumna Posted October 26, 2006 Posted October 26, 2006 hello, I think that you can use it for fountain compositions and so on. It´s a little bit to coarse for flashpowder´s. If u want to make Al-powder- or dust.... that would probably helpful: http://gamekeeper.deds.nl/metal_grinding_machine.html I hope it helps polumna
pa_pyro Posted October 26, 2006 Posted October 26, 2006 I would be leary of the water partially oxidizing the metal you intend to use.
aquaman Posted October 27, 2006 Posted October 27, 2006 That will have the same problem as grinding down Al foil in a blender with water as stated above ^^^^. Also the sand paper will put contaminates in the powder (aluminum oxide?). So it's not the best idea. The best I believe is just milling the Al with something that is harder then it for a couple of days.
Cherbanov Posted October 27, 2006 Author Posted October 27, 2006 i think i will try to ballmill it first and dosent that work for me then I will try the sandpaper, tanks for the tips evryone
