Rhenium

Its application is limited due to its availability. It is mainly used in small quantities to provide substantial benefits as an alloy additive: rhenium is a component with heat resistant superalloys.

Nickel-based superalloys are often used in jet engines where they are prized for their high strength.

Rhenium containing alloys can also be used in crucibles, self-cleaning electric contacts, electromagnets, ionization meters and spectrographs.
