Molybdenum-Rhenium Wire
 |
 |
Molybdenum-rhenium wire (Mo-Re Wire) is a high-performance alloy wire made from molybdenum (Mo) and rhenium (Re). The addition of rhenium significantly enhances the ductility, recrystallization resistance, and high-temperature strength of molybdenum. Mo-Re wires are widely used in aerospace, medical imaging, high-temperature electronics, thermocouples, and nuclear applications where extreme performance is required.
