- In this video I show how to make German dark aluminum powder from aluminum foil, charcoal, and a rock tumbler, and test it out in a few mixtures. Do not attempt this at home, Al powder can be dangerous to make if the mill is ran too long. Do not breathe this powder, it can irritate eyes and lungs. Mixtures stated can be dangerous if not handled/mixed correctly, don't ever attempt anything done in this video.
Nice, I made some aluminum powder in the same ball mill and being a kid at the time I didnt believe it would ignite.
I thought it only had a small chance so I just slowly opened the container and about 4 seconds later it lit. I tried to put it out by smothering it with a towel but I under estimated the metal fire, the towel immediately caught fire. Luckily I was able to scoop up the burning mess before the towel completely ignited and carry it outside.
I did this in an empty garage though so the fire would have been safe there on concrete floor but I didn't want the smoke to fill the house or my parents to know it happened.
I would not have opened the container indoors if it was wood flooring or flammable materials were nearby. Looking back at it I should have opened it outside anyway but I was just so excited at the time since i left the mill running for an entire week without peeking.
The mill survived since i dumped the fire out of the container but I didn't use it much since then because I got yelled at for wasting "TONS" of electricity and no matter what I said they didn't believe me that it barely uses any... i pulled up stats of how much electricity each household appliance use as well as showing them the math per kwh and even then they said I was wrong its using tons of electricity because its loud and I don't know anything im just a kid......
I have continued the hobby but have found many other hobbies and frequently switch between them all lol
This whole post smells of BS!
@@jibba0202 why bs? its a true story lol
So the power consumption is what , say 20 watts . A solar panel is no problem .
Have fun while your a kid, you’ll regret it later if you don’t. Trust me on that one. I’m old lol. You’ll only be a kid once.
Charcoal is added to the aluminum to prevent oxidization.Therefore your creating an aluminum powder that is extremely reactive.
What about the steel he is using😂
@@TheMulletMafia1 the oxygen inside gets used up but it's not the best choice of grinding media.
There is a way to speed up the milling process. You can take sheets of foil and run a propane torch over the shiny side gently (just enough to make it ductile, don't go full cherry red) and give it a couple minutes to cool. It is now much more brittle and easier for the mill to chew up. It doesn't measurably increase oxidation on the surface, as it is already oxidized (due to exposure to normal air) to a depth of a few atomic widths down below the surface, and if done properly, this won't change the final product. I'm able to get perfect airfloat after 48 hrs maximum. Also try fixing 3 or 4 "speed bumps" to the inside of the mill jar with epoxy. It'll lift the milling media higher up and give it more impact. Cheers!
*_Excellent tip!_*
Thank you for sharing…
This oxidizes it to make it much less effective.
How many grams do you make for 48 hours
How often to you open your container?
First tip is terrible idea . Second tip , creating lifters is a great idea. I did that and made a clear lid for my jar aswell as calculated proper rpm and adjusted my rock tumbler to match. And the milling speed increases by about 300%
I have the 6lb lortone ball mill jar that has 6 flat sides on the inside and use chromium ball bearings 1/2" about 200 of them and I'm getting these same results on 24 to 30 hours of milling. You need to upgrade your media and rpm of the mill to get a perfect crush. I installed a clear lid on mine and an adjustable motor control until it was perfect rpm. Nice vid.
Hey man where did you get a clear lid? I want to do the same thing as you
Or use proper alumina milling balls - cheaply available on eBay.
I got my mill to mill it to a perfect powder in two sets of 24hours, after the second milling I opened it and as I was observing it an ember formed and spread quickly, I quickly ran to through it while turned away and with my eyes closed, it was bright enough for me to see the brick wall behind me through my closed eyelids in the day. How could i prevent this from happening again
*Faster way.*
Blend the aluminium with a cup or more of water. For about an hour. The water will help cool down the aluminium and also makes smaller particles. Let the blender cool down once in a while. Keep blending until the water is Grey looking and the aluminium is all grinded. Pour it out into a dish. Let it dry until the water is all gone. Ball mill bigger pieces if needed or regrind them in the blender.
Enjoy
are you certain al didnt oxidized?
I recommend glass or ceramic marbles instead of steel h especially when it starts to become a fine powder - as the steel may also inadvertently cause a spark and then it can catch fire or explode
My neighbor gave me a box of stuff before he moved away and in the box was an unopened pound of aluminum powder -325 mesh in the manufacturers bag. Wondering how I can carefully turn it into dark aluminum powder. Or dispose of it in some way safely. Makes me nervous having this around the house. Especially this much.
i beilieve your composition of 95% al and 5% c is known as Aluminum powder 5413H-S aka the original dark aluminum powder
No trees were hurt in the filming of this...
i know that it's old but if anyone can this this comment i'd like to say
*Please DO NOT use metals for milling Aluminum Powder*
it can spark then light it which is very Dangerous
What are you gonna crush the aluminum with, rubber?
@@torturoustweak
It's not my problem if you don't know anything
Pyros knows that it's Dangerous to cruse it using metals
only Glass marbles are safe to use, and it's not that hard to search a little bit before replying to people.
I guess me and my ball mill were wrong all along. All that black powder, all that aluminum, wrong. Keyboard warriors, man...
@@torturoustweak Wow, your dense. It's literally common sense you don't use media like steel.
@@torturoustweak I really hope you aren't milling black powder like that
this is awesome, why do you only have 46 subs, your channel will get big, liked and subscribed:)
Well he has 77 subs now. Way to go Nostradamus.
If your going to play with flammable metals, be sure to keep a couple buckets of sand close by and/or a class D (for burning metals) fire extinguisher. Don’t use water on burning metals.
Says never attempt in the description. Yet, the title says"how to"... *Palmface.
Lmao xd kek
I’ve been in this hobby for a while but quick question, am I just able to use big stainless nuts? Or is there a sparking risk?
Yes there is a sparking risk try to use marbles they are much safer and does the job.
Lead fishing weights or balls are among the best media materials for milling powders, I've had great results with a 50/50 mix of 3/4" lead balls by weight mixed with 00-Buckshot, both of which I mold myself from shotgun molds (the 3/4" spheres are .73 roundball slugs). The lead has the mass to really push on things and it's softness helps the grinding action by digging the particles into the surface which increases roughness. And there is zero chance of sparking, lead is the safest media for milling too (from a flammability standpoint).
what isthe comp of the explosion in the end and how many grams
if i just get normal Al powder and mix in some charcoal will that work fine because here in Australia dar Al is illegal but normal is fine?
Bro you made a bomb ...
How manny gram Ammonal??
What's a safe way to store for a long period of time
Any sealed container will work fine. Ziplock bag, pickle jar, empty water bottle. As long as it can keep water/moisture out and the Al in.
@@exhilarator4314 why? Aluminum won’t ignite by static mr dumpyhead, hell, all the flash powders I have made don’t even ignite with a direct zap from a grill igniter
@@exhilarator4314 yeah yeah ofcourse, I’m not saying you shouldn’t be careful but I’m just saying it’s extremely unlikely even with flash powder so I think it’s basically impossible with aluminum powder unless you have a big cloud of it instead of just in a pile
what is the difference between dark al.powder and fine aluminum powder
@7.62x25mm so what is the chemical dif?
Dark aluminum is fine enough to oxidize in normal air based on a size between 5-3 micron, and being flake similar to a chip.
Normal powder used in ceramics and paints are spherical in shape and are roughly 30-15 microns depending on retailer.
Even though the sphereical has more surface area it will take a increased amount of energy to ignite.
Each has its uses in pyro but milled dark al is mostly used for flash comps where the energy to ignite is lower and in return a faster reaction is acquired.
Dark al gets its name from the charcoal added to prevent the rapid oxidation from occurring. There is bright al but I'm not quite sure what prevents its oxidation.
Theres also milled al covered in ferocerium giving it a blueish purple color again preventing oxidation.
James Luck great explation! I would not do it better.
A little late, but dark aluminium powder is basically aluminium powder coated in coal.
When you want very good flash powder, you need very fine aluminium powder, but if you powder your aluminium without coating it in coal, all you will get is pretty much just aluminium oxide, which is useless.
Also the coal acts as a second fuel.
You use the charcol that you grill with?
no use softwood charcoal
were i buy a ball mill?
you make em.... look it up on youtube :D

This is where I got mine:

@Фасист Евгенист 1488 Yeah I might be hella late to the party but I just finished making a ballmill and the total price (steel balls + the motor and other stuff) summed up to something like 30 bucks. Really not expensive and you don't need to pay any shipping either. If I would of looked around the house more I might of made it with less than 20 but I was lazy.
I've already tried this mixture. I can say for me that if I add crushed charcoal to aluminum powder there. That this results in quite poor quality shit completely unusable for FP. It works much better without charcoal. You just devalue the whole mixture with charcoal and I can throw it in the trash
You need air float charcoal preferably milled willow.
Try soot from a rich burning kero lantern ..lampblack.. From rich oxyacetylene flame its carbon black . Scrapings from a chiminey or flue .
That flash is bad I can make better with potassium nitrate
@@exhilarator4314 kno3 60% sulfur %30 magnesium 50%
bro that dark al not flash powder lol plus when combining with kclo4 it makes the best most stable flash powder for pyrotechnics
@@mta563 KClO4 flash powder is definitely better than nitrate flash but it isn’t more stable. 10g of it could blow your hand to bits
@@afbennett3038 not really kclo4 is very stable, you should treat all flash with care anyway so really you shouldn't have a problem.
@@mta563 compared to potassium nitrate it *is* less stable though. I get the feeling you have never dealt with nitrate flash, it’s a lot less scary
