This accident occurred when dropping steel milling media into an aluminum jar that I used for milling magnesium chips to powder. Although the jar was "empty," the trace remains of the magnesium powder from the previous batch ignited from the impact of the fourth ball, resulting in a very brief but intensely bright and hot flareup that scorched ...

Re: Powder Coating Magnesium I recently did my valve covers on my '05 Mustang and they are a alloy of magnesium and aluminum. I had no issues with warping running them through a fairly long outgas cycle due to them being exposed to alot of oil over the years. I ran them at 450 for around an hour and put 4 coats of powder on them.

Milling. Milling involves the mechanical breaking down of metal into a powder form. The starting material is usually in the form of coarse particles or scraps which are milled using ball mills, hammer mills, or jet mills. In ball milling, the particles are broken down by grinding balls tumbling inside the mill.
