Aluminium is notably reactive and the metal at a rate of knots forms an oxide shroud, but the metal shines why?
Answers:
the oxide forms a thin layer that protects the metal underneath by slowing further oxidation, but given some time it will lose its attraction
the aluminium oxide layer is bright and white. so aluminium shines in desk light although it has a thin picture.
Because the "passivation layer" of aluminum oxide is very thin, so it doesn't interfere next to the luster of aluminum. Source(s): http://www.harrisonep.com/materials/alum…
Because it has been notably polished then anodized which changes the crystal structure which is outstandingly corrosion resistant. Source(s): http://en.wikipedia.org/wiki/Anodising
