Overview of Molybdenum Alloy Properties
Molybdenum alloys are advanced metallic materials primarily composed of molybdenum (Mo) combined with elements like titanium, zirconium, rhenium, tungsten, hafnium, carbon, and other rare metals. These alloys are engineered to enhance the mechanical strength, thermal stability, electrical conductivity, and corrosion resistance of pure molybdenum, enabling exceptional performance under extreme conditions.
With its high melting point (2623°C) and low thermal expansion coefficient, molybdenum serves as a foundation for alloys that perform reliably in aerospace, nuclear, electronic, and high-temperature manufacturing environments.
Key Molybdenum Alloy Types and Their Properties
1. Molybdenum Rhenium (Mo-Re) Alloy
Composition: 11–50% rhenium.
Features enhanced ductility, weldability, and resistance to brittleness at low temperatures.
Exhibits superior creep strength and thermal stability up to extreme heat levels.
Applications: Rocket nozzles, turbine blades, electronic components, and nuclear reactor parts.
2. Titanium Zirconium Molybdenum (TZM) Alloy
Contains molybdenum with titanium, zirconium, and carbon additives.
Excellent strength, thermal/electrical conductivity, corrosion resistance, and low vapor pressure.
Applications: Aerospace engines, high-temperature dies, and glass processing components.
3. Molybdenum Copper (Mo-Cu) Alloy
Combines molybdenum’s mechanical strength with copper’s thermal and electrical conductivity.
Applications: Heat sinks, electronic contacts, and power semiconductor bases.
4. Molybdenum Tungsten (Mo-W) Alloy
Integrates tungsten’s hardness and wear resistance with molybdenum’s light weight and machinability.
Applications: High-speed cutting tools, furnace parts, and structural machinery under thermal stress.
5. Molybdenum Hafnium Carbon (MHC) Alloy
Offers superior creep resistance and thermal stability, ideal for nuclear and aerospace components requiring long-term high-temperature reliability.
6. Molybdenum Single-Crystal Alloys
Feature low brittle transition temperature and stable atomic structure.
Provide long service life and excellent radiation compatibility, ideal for nuclear power and defense applications.
General Properties and Benefits
Molybdenum alloys are widely recognized for their combination of mechanical robustness and thermal resilience, featuring:
High-temperature strength: operational stability up to 1650°C or beyond.
Superior thermal and electrical conductivity.
Low thermal expansion: ideal for integration with glass, silicon, and ceramics.
Excellent corrosion resistance against molten metals and chemical agents.
High tensile and fatigue strength.
Ease of machining and forming compared with tungsten-based materials.
Industrial Applications of Molybdenum Alloys
Because of their remarkable physical and chemical properties, molybdenum alloys are indispensable in:
Aerospace and defense: jet engines, turbine blades, and propulsion components.
Electronics: electrodes, heat sinks, filaments, and semiconductor mounts.
Nuclear engineering: reactor shielding, fuel containment, and radiation-resistant structures.
Glass and metallurgy: melting electrodes, crucibles, and extrusion molds.
Automotive and precision tools: cutting dies, mold inserts, and wear-resistant parts.
These alloys deliver consistent performance and durability in high-stress, high-heat industrial environments.
