Overview of Molybdenum Alloys
Molybdenum alloys are advanced materials composed mainly of molybdenum (Mo) combined with elements such as titanium, zirconium, rhenium, tungsten, hafnium, and carbon. These alloying additions are engineered to significantly enhance molybdenum’s mechanical, thermal, and chemical properties—especially under extreme temperatures and corrosive environments.
With a melting point exceeding 2600°C, molybdenum-based alloys provide a unique combination of strength, stability, and thermal conductivity, making them indispensable in aerospace, nuclear energy, and high-temperature industrial processes.
Common Types of Molybdenum Alloys and Their Properties
1. Molybdenum Rhenium (Mo-Re) Alloy
Contains 11–50% rhenium, which improves ductility, weldability, and resistance to brittle fracture.
Excellent creep strength and stability at elevated temperatures.
Applications: rocket nozzles, turbine blades, thermocouples, and nuclear reactor components.
2. Titanium Zirconium Molybdenum (TZM) Alloy
Composed of molybdenum with 0.5% titanium, 0.08% zirconium, and 0.02% carbon.
Features high tensile strength, corrosion resistance, and low thermal expansion.
Widely used in aerospace engines, high-temperature dies, and glass melting electrodes.
3. Molybdenum Copper (Mo-Cu) Alloy
Combines molybdenum’s mechanical strength with copper’s thermal and electrical conductivity.
Ideal for heat sinks, electrical contacts, and thermal management in power electronics.
4. Molybdenum Tungsten (Mo-W) Alloy
Integrates tungsten’s hardness with molybdenum’s machinability and lower density.
Common in cutting tools, furnace parts, and structural components exposed to high temperatures.
5. Molybdenum Hafnium Carbon (MHC) Alloy
Offers superior creep resistance and high-temperature strength, making it suitable for aerospace propulsion and nuclear technology.
Advantages of Molybdenum Alloys
High-temperature performance (usable up to 1650°C and beyond).
Excellent thermal and electrical conductivity.
Corrosion resistance against molten metals and glass.
Low coefficient of thermal expansion — compatible with glass, silicon, and ceramics.
High tensile and fatigue strength with low creep deformation.
Better processability compared with pure tungsten alloys.
These combined properties make molybdenum alloys highly valuable for extreme service environments.
Applications of Molybdenum Alloys
Molybdenum alloys play a vital role in numerous industries:
Aerospace: jet engine parts, turbine blades, and rocket components.
Electronics: electrodes, semiconductors, and heat sinks.
Nuclear energy: reactor components and radiation shields.
Glass and metallurgy: melting electrodes and extrusion dies.
Automotive and tooling: high-speed cutting tools, dies, and precision molds.
Their durability, conductivity, and stability under harsh conditions ensure longevity and performance in critical systems.
