Rhenium is chemically similar to manganese and is a by-product of the extraction and refining of molybdenum and copper ores. Rhenium displays a variety of oxidation states from -1 to +7 in its compounds.

Rhenium-nickel-based superalloys are used in jet engine combustion chambers, turbine blades and exhaust nozzles.

These alloys contain up to 6% rhenium, making jet engine manufacturing the largest single use of the element, with catalytic uses in the chemical industry the second most important. of. Due to low supply relative to demand, rhenium is one of the most expensive metals, with an average price of approximately $4,575 per kilogram ($142.30 per troy ounce) as of August 2011; it also has crucial It is of strategic military importance because it is used in high-performance military jet and rocket engines.
