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
allots with with iron, nickle and cobalt.
The symbol for Chromium is Cr. The atomic
number is 24. Its melting point is at 1857 degrees celsius
