You might not be familiar with the term “superalloy”, but it describes any alloy where resistance to high temperatures or severe mechanical pressure is important. 

Examples of where they are used include space vehicles, jet engines, rocket motors, nuclear reactors or in power stations.

Cobalt-based superalloys have the highest melting point when compared to nickel or iron-based superalloys, as well as superior heat corrosion resistance and batter resistance to thermal fatigue.

In short – when you next get on a plane, or perhaps if you one day go into space in a rocket – you might well have cobalt to thank for getting you to your destination safely.
