Magnesium Rod

Designed for demanding environments, Goodfellow's Magnesium Rod combines ultra-low density with high specific strength - ideal for aerospace, automotive, biomedical, and energy applications. Manufactured from 99.9% to 99.97% pure magnesium with diameters up to 76 mm and lengths up to 1000 mm, it offers excellent machinability and structural stability. Magnesium’s high thermal conductivity supports efficient heat transfer in heating systems and mineral-insulated copper-clad (MICC) cables, while its electrochemical activity enables reliable sacrificial anode functionality in cathodic protection. Non-magnetic and biocompatible, it’s also a promising material for biodegradable implants and precision components in sensitive electronic systems. With exceptional vibration damping, clean combustion, and alloying potential, our magnesium rod is an ideal material for structural parts, coatings, and ignition systems.
