A hard, ductile and ferromagnetic metallic element, highly polished and resistant to corrosion. Nickel belongs to the iron-loving element. It contains the highest nickel in the earth's core and is a natural nickel-iron alloy.

In the crust, ferromagnesian rocks contain more nickel than silicoaluminous rocks. For example, the nickel content of peridotite is 1000 times that of granite, and that of gabbro is 80 times that of granite.

Physical properties of nickel:

Good ductility and moderate hardness.

Nickel is a silvery white metal with magnetism and good plasticity.

Nickel has good corrosion resistance, almost silvery white, hard, malleable, ferromagnetic, highly polished and corrosion-resistant. Soluble in nitric acid, green.

Mainly used in alloys (such as nickel steel and nickel silver) and as catalysts (such as raney nickel, especially as hydrogenation catalysts).
