tungsten. This gives it a hardness which is good for this job.
Since it is lustrous and hard to corrode, it is used in the body
trim of many vehicles. It is also used for this reason and many
others because of its high melting point and the stability of its
crystalline structure. The chief use, of chromium is to form

Chromium was discovered by the, French chemist
Louis Nicolas Vauquolin in the year 1797, who named it after
"chroma", the greek word for color since, it is also found in some
precious gems. Vauquelin was very excited with discovery, also
because, he was better at finding things dealing with science,
than his master when he was just a small aprentice. Vauquelin
also went on to discover a lot more chemicals and bonds later
in his life time.|
