Nickel (Ni)

Nickel is the sixth most abundant element on Earth, with one of its biggest uses being in bringing ductility and corrosion resistance to stainless steel. As such, it is more appropriate to discuss nickel as an ingredient in many alloys rather than as a stand-alone metal.

Nickel is a ductile, silvery white metal with a good resistance to corrosion. However, when it is alloyed to other metal ingredients, like steel, chromium and titanium, its properties are enhanced to produce what are known as superalloys. One major area of application is for aircraft engines, where nickelbased superalloys are used in the hottest parts of aircraft engines, where temperatures exceed 16000ºC (28832ºF). Alloyed with chromium in the proportion of 18 per ...
