Rhenium is a silvery metal but rarely seen as such on account of its high melting point, which is the third highest after carbon and tungsten.Resistant to heat, corrosion and thermal shock, and possessing excellent electrical resistivity, rhenium is the ideal material for both project and production applications. Rhenium provides excellent wear resistance, which means increased reliability and greater dependability.

Rhenium is used as an important component in superalloys for blades in turbine engines and this is the major use today. Rhenium is an ideal metal for use at very high temperatures, which makes it suitable for rockets motors. Rhenium is added to tungsten and molybdnum to form alloys that are used as filaments for ovens and lamps. It is also used in thermocouples which can measure temperatures above 2000 C, and for electrical contacts which stand up well to electric arcs.
Rhenium, alloyed with platinum, was used in petroleum-reforming catalysis in the production of high-octane hydrocarbons, used for lead free gasoline.

Other applications are rhenium-tungsten alloys in X-raytubes and rotating X-ray anodes. Rhenium-molybdenum alloys are superconductors at a temperature of 10K. Rhenium has occasionally been used for plating jewerly.
