A great discription of things, and I thnk your facts are good, except 
for that part about
Aluminum oxide being flammable.  
Aluminum oxide is what protects aluminum from corrosion,  because it is 
very inert.  As an oxide,
it's already "burnt".  If you melt it down under great heat,  it makes a 
glassy materiel known as
Sapphire...

But other than that,  a good description..
