Magnesium solids will not normally combust when exposed to flame. My experience machining magnesium thorium gearcases in the 80's for GE (B1 Bomber) showed that we had to contain and control the dust and chips from the machining. We had powder extinguishers and all personnel in the CNC machining Cells were trained and certified to extinguish mag fires.
Certainly a sustained high intense heat source from the fuel in a racing wreck would probably cause any magnesium to join in the combustion process. I purchase magnesium extrusions for concrete tools today and it is the chips, dust, and moisture that I have to control to keep my operation safe. |
