Products Description
Our tzm alloy rod is an advanced grade alloy of molybdenum (Mo) which incorporates titanium (Ti), zirconium (Zr), and small amounts of carbon, C. Its name comes from the symbol of the component elements (Titanium-Zirconium-Molybdenum). This alloy undergoes a remarkable improvement in the high-temperature strength and recrystallization temperature of pure molybdenum by solid solution strengthening and carbide dispersion strengthening. It is a core material in the fields of aerospace, nuclear industry and semiconductor equipment.
Features of TZM alloy round bars:
| Characteristics | Value/Performance | Comparison with Pure Molybdenum |
| Melting Point | 2610°C | Similar to pure molybdenum (2623°C) |
| High-temperature Strength | Strength ≥300 MPa at 1200°C | 30% higher than pure molybdenum |
| Recrystallization Temperature | 1400–1600°C (higher than pure molybdenum) | Pure molybdenum is about 1000–1200°C |
| Thermal Conductivity | 142 W/(m·K) (at room temperature) | Comparable to pure molybdenum |
| Oxidation Resistance | Requires coating protection (such as molybdenum silicide) | Same as pure molybdenum |
Applications of TZM alloy round bars include:
🔹 Semiconductor manufacturing equipment
Ion implanter parts: beam collimator, high temperature fixture (plasma corrosion resistant).
Wafer heater: uniform heat field, thermal shock resistance (diameter is usually 50–200mm).
🔹 High temperature industry
Sintering furnace heating element: long-term use in 1600–1800°C environment.
Glass melting electrode: replace platinum alloy and reduce costs.
🔹 Aerospace
Rocket nozzle bushing: high thermal shock resistance (nickel plating protection after round bar machining).
Turbine blade coating substrate: surface coated with thermal barrier coating (TBCs).
🔹 Nuclear industry
Nuclear fuel sintering mold: radiation resistant and low neutron absorption cross section.

FAQ for TZM alloy round bar
1. What is TZM alloy?
A: TZM is a molybdenum-based high-temperature alloy, usually composed of Mo-0.5Ti-0.1Zr (containing a small amount of titanium and zirconium). It has higher high-temperature strength, creep resistance and recrystallization temperature than pure molybdenum, and is widely used in extreme high-temperature environments.
2. What are the main advantages of TZM round bars?
✅ High-temperature performance
✅ Mechanical strength
✅ Corrosion resistance
✅ Thermal conductivity
3. What are the typical applications of TZM round bars?
Semiconductors
Aerospace
Industrial furnaces
Nuclear energy
What are key points of manufacturing process ?
Powder metallurgy
High-purity molybdenum powder + TiH₂/ZrH₂ mixed → isostatic pressing → hydrogen sintering (2200°C).
Smelting and purification
Electron beam melting (EBM) removes low melting point impurities (such as Fe, Ni).
Thermomechanical treatment
Hot extrusion (1200°C) → multi-pass cold drawing (processing rate ≥90%).
5. What is the MOQ?
A: Depends on quantity, generally, no MOQ limit.
6. How to pay for it?
A: A bank transfer (T/T) will be acceptable.
7. What is the delivery time?
A: around 7-20 days which depends on the quantity and production.
8. What is the package?
A: carton case or plywood case.
9. What is the lead time?
A: from order placed to cargo receiving will take around 10-25 days.
10. What is the delivery method?
A: Generally, we send cargo by UPS, DHL or FedEx. Also, we can send by sea to seaport or by air to the closest airport.
