   As will many other things.  The ease or difficulty of ignition is   
   important, though.

   Aluminum burns fiercely in LOX, and is not even that hard to ignite. Even   
   stainless *will* burn in LOX, but it needs much more provocation.   
      
   The Apollo 13 tank rupture was due to PTFE/Teflon -- or rather, Teflon   
   breakdown products -- burning in supercritical LOX.
