Application
Small quantities of rhenium are alloyed with iron to form steel that is both hard and resistantto wear and high-temperatures. Because of its high melting point, rhenium is used inmany applications where long-wearing, high-temperature electrical components are required,such as electrical contacts and switches and high-temperature thermocouples. This physicalquality makes rhenium alloys ideal for use in rocket and missile engines. It is also used to formthe filaments in photographic flash lamps.Rhenium's isotope (187Re) has a very long half-life and decays by both beta and alpharadiation at a very steady rate. This factor makes it useful as a standard to measure the age ofthe universe.
