Description of Molybdenum Alloy TZM Bar

Molybdenum Alloy TZM Bar is an alloy material composed of molybdenum, titanium, and zirconium. It has high strength, high recrystallization temperature, excellent high-temperature oxidation resistance, and strong corrosion resistance. It is an important superalloy material.

Molybdenum Alloy TZM Bar has excellent mechanical properties and thermal stability at a high temperature of 3000°C, so it can be widely used in high-temperature and high-pressure fields such as aerospace, shipbuilding, petrochemical, nuclear industry, and metallurgical manufacturing.

In the field of aerospace, Molybdenum Alloy TZM Bar is often used to manufacture spacecraft engine nozzles, turbine blades, and other components. In the petrochemical industry, it is very suitable for manufacturing key components of high-temperature and high-pressure equipment, such as high-temperature furnace tubes and catalyst carriers. It is very suitable for use as support frames, heat exchanger components, and rails on nuclear energy equipment. It should be noted that the processing of TZM is more difficult and costly, and should be selected according to specific application requirements.

Features of Molybdenum Alloy TZM Bar

Ultra-high melting point and high temperature strength

The melting point is as high as 2610°C, and it still maintains high strength (better than pure molybdenum by more than 30%) in the range of 1200°C~1600°C, and has excellent creep resistance.

Excellent thermal shock resistance

Low thermal expansion coefficient (4.8×10⁻⁶/°C) and high thermal conductivity (142 W/m·K), can withstand rapid temperature changes (such as thermal shock during rocket engine ignition).

Good corrosion resistance

Resistant to molten metals (such as copper and aluminum), excellent stability in non-oxidizing atmospheres (such as vacuum and inert gas), but requires coating protection in oxidizing environments.

Work hardening characteristics

High hardness at room temperature (HV≥250), high-temperature hot processing (such as hot rolling and hot forging) is required, but plasticity can be improved by annealing.

Applications of Molybdenum Alloy TZM Bar

1. Aerospace and military industry
Rocket engine nozzle/throat lining: withstand ultra-high temperature gas erosion (such as SpaceX Merlin engine nozzle parts).

Missile end cap/reentry vehicle leading edge: use its anti-ablation performance to resist the extreme heat load during atmospheric reentry.

Satellite thrust chamber: high-temperature structural parts for ion thrusters.

2. High-temperature industrial equipment
High temperature furnace heating element/heat shield: used as a high temperature support in semiconductor sintering furnaces and sapphire crystal growth furnaces.

Glass melting furnace electrode: resistant to molten glass corrosion, life far exceeds that of a graphite electrode.

Hot isostatic pressing (HIP) sleeve: used in high-pressure and high-temperature environments for titanium alloy powder molding.
