Product Overview
Molybdenum rod is a molybdenum-based metal bar characterized by an extremely high melting point, excellent thermal conductivity, low thermal expansion coefficient, and outstanding corrosion and high-temperature resistance. Available in various forms including forged, polished, and as-rolled conditions, with compositions ranging from pure molybdenum to specialized alloys like TZM (Ti-Zr-Mo).

Selection & Processing Guidelines
Dimensions & Tolerances: Custom specifications available from φ0.8 mm – 250 mm, length ≤3000 mm per GB/T 4188-2017, with tolerances according to GB/T 4188-1984
Surface Treatment:
As-rolled (retaining processing lubricants and oxide layer) for direct use in high-temperature furnaces
Chemically cleaned (oxide layer removed) presenting silver-gray brightness for precision electronic components
Polished (mirror finish) for optical and vacuum applications
Heat Treatment: 850°C – 950°C annealing eliminates residual stress and improves elongation; TZM alloy recommends 1050°C annealing for optimized high-temperature strength
Packaging: Individual PE foam wrapping in wooden crates with void fill to prevent transportation damage
