Molybdenum and Rhenium metaux-materiauxspeciaux

Rhenium is quite a rare metal: its concentration is about 0.7 ppm in the earth's crust. It is the last naturally occuring element to be discovered (1925). Most rhenium today is produced as a by-product of the copper mining industry: rhenium is found in those copper ores contaminated with molybdenum.

Molybdenum Rhenium Alloy (MoRe)

MoRe® is a highly pure alloy containing only two elements- Molybdenum and Rhenium. Rhenium was discovered only recently (1925) and is the last stable non-radioactive element discovered. MoRe® has its roots in aerospace where its high strength and fatigue resistance has overcome many of the limitations of traditional materials.
