Historie
Artifacts made from metallic meteorites have been found dating from as early as 5000 BC.
In 1751, Baron Axel Fredrik Cronstedt was trying to extract copper from kupfernickel and instead produced the white metal.
In the early twentieth century, Ludwig Mond patented a process using nickel carbonyl to purify nickel.

Applications
Nickel is used extensively to make coins and nickel steel for armor plates and burglar-proof vaults.
Tubing made of copper-nickel alloy is extensively used in making desalination plants for converting sea water into fresh water.
Nickel is also used in batteries, ceramics and magnets.
