TZM Alloy Molybdenum Rod MoTiZr Rods Surface Machined / Ground 5mm to 100mm
TZM alloy rod has a higher recrystallization temperature, higher strength, hardness and good ductility at room and elevated temperatures than unalloyed Molybdenum. In addition, TZM exhibits good thermal conductivity, low vapor pressure, good corrosion resistance and is machinable.
TZM Alloy Rods Used In Typical Areas:
Components for HIP, sintering and heat treatment furnaces
Metals for rotating anodes for medical diagnostics
Boats for annealing and sintering processes (temperatures up to 1400 °C)
Forming tools such as hot runner nozzles for plastic injection moulding
Moulds for light-alloy casting
Billets for the isothermal forging
TZM alloy has a high recrystallization temperature, high strength, hardness than unalloyed molybdenum at room and elevated temperatures and good ductility. Furthermore, TZM has good thermal conductivity, low vapor pressure, good corrosion resistance, so can be processed.
And molybdenum TZM alloy has a higher recrystallization temperature than pure molybdenum has a higher heat resistance, better creep resistance.
Specification of TZM Rods:
Mo content: Mo>=99.95%
Density: >=10.1g/cm3
Dia: 5.0 - 100mm
Surface: polished, ground, cleaned
Black – Surface is “as swaged or “as drawn”; retaining a coating of processing lubricants and oxides.
Cleaned - Surface is chemically cleaned to remove all lubricants and oxides.
Ground - Surface is centerless ground to remove all coating and to achieve precise diameter control
