IME they're really not all that dense. When chips come off a lathe or mill cutter they are curled and have small serrations in them where the sharp edge cracked as it was curling. So they don't pack well. Each chip takes up a large amount of 3D space and they interlock really easily--they don't slide past each other.

ah that's where you're coming from (see my other comment)

iron and steel chips still are about 2 kg/l

aluminum is 200g / l

so one 55gal trash bin is still about 40 something kg, four dozen.

so for aluminum and aluminum only it may be multiple trash bins

This still sounds hard to sneak into a warship’s oil system though.
