Basic chemistry; Aluminum is very reative, and burns easly. At first glance aluminum may seem to resist burning well. But that is more the layer of aluminum oxide, coupled with aluminums ability to wick away heat quickly.
Aluminum is so reative to oxygen that exposure to air immediatley forms a layer of alum-oxide; which seals the aluminum (passivate - word of the day) from futher "burning" . . .unless the temps are so high the reaction continues.
Too bad aluminum can't take the heat; SSI's would be a lot lighter.
