Rhenium has several unique properties as follows:
High melting temperature
Extreme resistance to chemical erosion
Ability to maintain ductility after recrystallization
High electrical resistivity over a wide temperature range
Low vapor pressure
Resistant to oxidation at very high temperature
Good thermal shock resistance
W-Re alloys are made of Tungsten alloyed with 3%, 5%, 25% or 26% Rhenium, which become more ductile and machineable. With good electrical properties, W-Re alloys are widely used as high temperature thermocouple materials.
Mo-Re alloy is Molybdenum Alloyed with 41% or 47.5% of Rhenium (nominal content of Rhenium is 50%), which has good ductility, weld ability, formability, and strength. Mo-Re alloy keeps high ductile even after used in high temperature. Mo-Re alloys are widely used for electronics, nuclear, and space applications.
