Overview
TZM molybdenum alloy rod is a high-temperature alloy product based
on molybdenum, with additions of approximately 0.5% titanium, 0.08%
zirconium, and trace amounts of carbon. It exhibits excellent
high-temperature strength, creep resistance, weldability, and
machinability, making it suitable for manufacturing critical
components used in extreme high-temperature environments across
sectors such as metal hot working, aerospace, the nuclear industry,
high-temperature equipment, electronic devices, and medical
applications.
Features
- Outstanding high-temperature strength and creep resistance: Even at
extreme temperatures ranging from 1000°C to 1400°C, it maintains
high strength and structural integrity, with minimal deformation or
softening, effectively preventing premature failure due to creep in
components.
- Excellent thermal conductivity and thermophysical properties: It
allows for efficient heat dissipation and ensures the stable
operation of equipment. It also features a low thermal expansion
coefficient, high melting point, and low vapor pressure,
demonstrating excellent fatigue resistance under repeated heating
and cooling cycles.
- Superior corrosion resistance: Highly suitable for harsh
environments such as chemical plants and the oil and gas industry.
With its extended service life, high reliability, and reduced need
for downtime maintenance, it offers higher overall
cost-effectiveness in applications involving extreme temperatures.
- Good ductility and machinability/weldability: It can be processed
into parts of complex shapes using conventional cold working
methods and welds well with various materials, significantly
improving production efficiency and assembly flexibility.

Application
1. Metal hot processing field
TZM Rod is the core material for aluminum and copper alloy and cast
iron die casting molds, especially suitable for forming
high-melting-point metals. Its high creep resistance can
significantly extend mold life and prevent product accuracy loss
caused by deformation at high temperatures.
Used for hot extrusion piercing processes of stainless steel and
other metals, maintaining structural stability in high-temperature
environments above 1200°C, avoiding perforation failures caused by
softening.
2. Aerospace sector
TZM Molybdenum Alloy Rod, as a material for rocket nozzle throat
linings, combustion chamber nozzles, and gas pipes, can withstand
extreme temperatures (above 1400°C) and high-speed gas scouring
generated by rocket propellant combustion, while its low thermal
expansion coefficient ensures dimensional stability of components.
TZM Rods are used to manufacture special engine valve bodies,
thermal protection system brackets, and more, meeting the
structural strength requirements of aerospace vehicles in
high-temperature environments.
3. High-temperature equipment and stove manufacturing
Molybdenum High Temperature Alloy TZM Rod serves as a core
component of thermal isostatic presses (HIPs), including insulation
screens, heating element brackets, and high-pressure chamber
structures, maintaining stable performance at temperatures above
1500°C and high pressures of 100-200MPa.
Manufactures key components of high-temperature sintering furnaces
such as sintering boat vessels, furnace supports, and heating
elements, suitable for high-temperature sintering processes of
ceramics, cemented carbide, and other materials.
4. Other applications
Used for high-power electron tube gates and X-ray tube rotating
anodes for medical devices.
Used to manufacture heat exchanger components, radiation shielding
structures, and high-temperature fuel element support frames, its
corrosion resistance and neutron radiation resistance surpass those
of traditional materials.
In glass melting furnaces, it is used as an electrode material and
directly contacts molten glass at 1300°C, ensuring long-term stable
operation due to its corrosion resistance.
