Eric, having worked with magnesium and its alloys for some years, let me assure you that only the very purest of magnesium can be ignited with a match. Commercial magnesium is almost exclusively alloyed to eliminate this property, usually with as little as 1% zinc which renders it unignitable, at least with common ignition sources.





I just remember as a kid, my father bought an old combine for salvage that had aircraft tires and wheel on it. When dad went to torch out the steel hub from the "aluminum" rim, the thing burst into flames. He goes, and I quote "I guess those are made of magnesium, I'd better not do that again!" The whole thing, tire and all, was gone in about 5 minutes. Of course, a propane torch isn't a "common" ignition source.
