Airplane turbine blades are made of nickel alloys--mainly nickel with chromium and cobalt.

Margarine is a butter substitute made from liquid oils by hydrogenation. A nickel catalyst speeds up the reaction. Unsaturated fats in the oils (ones with double bonds between some of the carbon atoms in the carbon chains) become saturated when hydrogen is added. A nickel catalyst makes the reaction fast enough to be economically viable. The resulting saturated fat has a higher melting point making the margarine a solid at room temperature.

The outside of the Mercury capsule is made of a specialised, high-temperature nickel-steel alloy called Rene 41
The capsule was photographed at the National Air and Space Museum, Steven F. Udvar-Hazy Center, Chantilly, Virginia, USA
