Rhenium (Re) is a refractory transition metal with exceptional high-temperature stability and one of the highest melting points of all elements. It is used primarily in superalloys for aerospace engines, as a catalyst in petroleum refining, and in electrical contact applications where extreme thermal resistance is required. Engineers select rhenium when conventional nickel- or cobalt-based alloys reach their temperature limits, though its high density, cost, and scarcity make it a material of last resort reserved for critical, high-performance applications.
