Aluminum powder from soda cans Answered

I was wondering what would be a good way to obtain aluminum powder from soda cans 
I have a ball mill 
and why buy foil when cans are free
any ideas? ive already tried cutting it in to small strips and blending it but that doesn't work 


How much powder are you planning to make? Cause that's gonna be a lot of sodas to drink...

I just take a nail file to the tabs

And that is why you need to have it in a thin foil thickness. You can spend your time hammering out your cans into foil strips, unless you have hydraulic rollers.
