Molybdenum Rod

Goodfellow's Molybdenum Rod is a dense, cylindrical form of the refractory metal molybdenum, offering exceptional resistance to extreme temperatures, corrosion, and mechanical stress. With a melting point of 2623 °C, thermal conductivity exceeding 130 W/m·K, and outstanding dimensional stability, it performs reliably under high vacuum and oxidizing or reducing atmospheres. Its primary applications span aerospace thrust components, nuclear shielding, high-temperature furnace fixtures, and ion-implanted semiconductor tooling. Notable uses include sintering furnace shafts, x-ray target backings, RF heating elements, and structural supports for precision optics. Molybdenum rods are also pivotal in R&D for thermoelectric energy harvesting, corrosion-resistant coatings, and the design of neutron-moderating assemblies. Their capacity to maintain mechanical properties under cyclical and static thermal loading makes them indispensable in studying thermo-mechanical fatigue, phase transformation kinetics, and diffusion bonding. As a platform material in materials science and high-temperature engineering, the molybdenum rod supports innovations in both industrial manufacturing and next-generation energy technologies.
