Rhenium. More than 80% of the global rhenium usage is in high-temperature superalloys for aircraft applications like turbine blades and engine parts. These alloys contain up to 6% rhenium, making jet engine construction the largest single use for the element. Rhenium is added to nickel-based super alloys to improve creep strength of the alloys.
