Pillow,
Aluminum does indeed burn. If you take aluminum dust and ignite it, it burns with the brilliance of magnesium powder. If you've ever seen a belly landing, you will see aluminum sparking (burning). Granted it is softer than steel and not as prone to spark but it does as Titan has stated. If you want, I can get you the flash point of aluminum.

being a -300, it had a tail skid, unlike the -200. anyway, the damn thing sticks out about a foot and a half. apparently, the skid touched the runway surface, but did not get deflected enough to activate the TAIL STRIKE message. all this according to the tower. in otherwords, if there was no tail skid, they would never have hit the ground. they would have been BLOODY CLOSE!!! but they wouldn't have struck anything. anyway, they had no indication to tell them that the skid had licked the runway, and they went on. by the way, non-local, non-asian commander flying the plane at the time. therefore must have been the plane's/airport's/FO's/iran's/muammar gaddafi's/anyone else's, but not the pilot's fault.
just kidding!!! hahahaha......
cheers.

Barring lab condition , the only metals that burn is magnesium , sodium and potassium . Magnesium is used on some engine gearbox .
Sparking is different from burning .
Anyone who have used a grinding wheels knows that iron/steel sparks but not aluminium . ( It is illegal to grind aluminium )
In a belly landing , the sparks you see is probably from the brakes , landing gears , engine cowlings or engines .
Titan , read the Structural Repair manuals if you want to know more about aluminium alloy .
Cheers

A little bit of knowledge is dangerous.
Alumumium DOES burn(oxidises; look at the remains of any aircraft accident after there has been a fire - you don't see much do you?
One does not use aluminium with a grinding wheel because it fuses amongst the carborundum particles causing stress and the possibility of the wheel coming apart.
BUT MOST OF ALL, THEY DON'T MAKE TAIL STRIKE PADS OUT OF ALUMINIUM!!!!!

In the 1980's SIA had a policy of never publishing details of its (many) incidents to any of its crews - only the briefest mention of incidents appeared in the Safety Digest. This was because they felt that any adverse publicity could be used by their competitors. They had no compunction about publishing full details of any other airline however and their Flight Safety magazine was full of OTHER airline accidents and incidents. Do they still have this policy ? Their crews had to learn from other airline mistakes, never from their own. If they had a tail strike at SYD they would want to keep it under wraps too. NOT a good safety culture !

I said ....... Steel/iron spark , aluminium dont
you said ..... aluminium burns
I said ....... there is a difference between sparking and burning
you said ....... aluminium burns
That was an excellent text book answer on aluminium grinding . Full mark !!!!
If you do want to grind aluminium , Use a grinding belt .
Your next assignment is to find out WHY IRON/STEEL SPARKS .
Hint 1 Pure iron do not spark !
hint 2 cast iron sparks a lot more than steel
Hint 3 Run your finger along a cast iron and your finger turns black/dirty
Hint 4 Cast iron is brittle and steel is tough
Hint 5 pure iron is soft
