TZM Molybdenum Alloy Rod

TZM molybdenum alloy rod is a high-strength alloy material based on molybdenum with titanium, zirconium and a small amount of carbon. Compared with pure molybdenum, TZM alloy has a higher recrystallization temperature, higher strength and hardness at high temperatures, and has sufficient ductility. This alloy occupies an important position in the aerospace and military fields due to its excellent mechanical properties.

TZM Molybdenum is an alloy of 0.50% Titanium, 0.08% Zirconium, and 0.02% Carbon with the balance Molybdenum. TZM Molybdenum is manufactured by either P/M or Arc Cast technologies and is of great utility due to its high strength/high-temperature applications, especially above 2000F.

TZM Molybdenum has a higher recrystallization temperature, higher strength, hardness, good ductility at room temperature, and elevated temperatures than unalloyed Molybdenum. TZM offers twice the strength of pure molybdenum at temperatures over 1300C. The recrystallization temperature of TZM is approximately 250°C, higher than molybdenum, and it offers better weldability. In addition, TZM exhibits good thermal conductivity, low vapor pressure, and good corrosion resistance.

TZM Alloy rod can also be named as: TZM molybdenum alloy rod, titanium-zirconium-molybdenum alloy rod.

We can also provide machined TZM Alloy parts per drawings.

What is the difference between TZM alloy rod and pure molybdenum rod?
A: TZM has significantly better high temperature strength, recrystallization temperature and creep resistance than pure molybdenum due to the addition of Ti and Zr, but the cost is higher.

What are the typical specifications of TZM rods?
Diameter: Common 3mm~100mm, length can be customized (usually ≤500mm).

Surface state: black skin (sintered state), polished, centerless grinding (precision grade).

Will TZM rods oxidize at high temperatures? How to protect?
A:

It is easy to oxidize above 500°C and needs to be used in an inert atmosphere (such as argon) or vacuum environment.

Anti-oxidation coating (such as silicide) can be applied on the surface.

What is the procurement cost of TZM rods?
A: The price is affected by purity, size and processing accuracy, and is usually 1.5~2 times that of pure molybdenum rods.

Can TZM rods replace tungsten alloy?
A: Below 1200°C, TZM is more cost-effective (lower density and easier to process); above 1600°C, tungsten alloy is more suitable.

Are you a factory or manufacturer?
A: Yes, we are a factory but generally, we use our trading company to handle the business abroad. It will be convenient to receive the remittance and arrange the shipment.

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.

Why is your product so cost-effective?
A: We cut out the middlemen in the end-to-end manufacturing process. Rather than obtaining semi-finished goods from other suppliers, we obtain our raw material of APT powder directly from its source.

Do you do spot quality inspection or full inspection?
A: 100% full inspection. Inspectors will check the finished product individually, to ensure they adhere to all parameters. All unqualified products are discarded.

How do you ensure your lead time?
A: We have an efficient Order Management System, from material preparation to machining, and finally to a full inspection. Every stage of production is strictly monitored and controlled to give you an accurate delivery time.

What is the MOQ of (xxxxxx)?
A: Depends on quantity, generally, no MOQ limit.

How to pay for it?
A: A bank transfer (T/T) will be acceptable.

What is the delivery time?
A: around 7-20 days which depends on the quantity and production.

What is kind of the package?
A: Generally, we use a carton case or plywood case with protective material inside to ensure the save of cargo

What is the lead time?
A: from order placed to cargo receiving will take around 10-25 days.
