Advantages of Molybdenum Alloy
Strength-to-weight ratio:
One of the most remarkable attributes of molybdenum alloys is their strength-to-weight ratio. As a matter of fact, molybdenum is used in the structural components of aircrafts, with the idea of maintaining a lower weight of the craft while still keeping up its structural integrity.
Temperature resistant:
It should probably go without saying that extreme temperatures are frequently encountered in the aerospace industry, especially in parts of the aircraft such as the engines and the propulsion motors.
Resilient against corrosion:
The various components of an aircraft can be highly susceptible to corrosion due to the harsh conditions that they tend to go through, which more often than not can include increase in moisture as well as exposure to various chemicals.
Insulation from radiation:
Molybdenum is an essential component of radiation shielding materials used in space travel, where astronauts are subjected to cosmic radiation. It helps in shielding astronauts as well as their equipment from this potentially dangerous radiation, ensuring their safety during space flights.
Types of Molybdenum Alloy
Molybdenum-Tungsten Alloy (Mo-W): Molybdenum tungsten alloy combines the strength and heat resistance of molybdenum with the hardness of tungsten. It's ideal for cutting tools and high-performance machinery because it is very durable.
Molybdenum-Rhenium Alloy (Mo-Re): Known for its exceptional high-temperature strength and creep resistance, molybdenum rhenium alloy is ideal for rocket nozzles, turbine blades, and nuclear reactor components, where it withstands extreme heat and radiation.
Molybdenum-Copper Alloy (Mo-Cu): Molybdenum copper alloy has great thermal and electrical conductivity, making it suitable for electronic and electrical applications where efficient heat and electricity transfer are needed.
TZM Alloy (Titanium-Zirconium-Molybdenum): TZM alloy includes titanium and zirconium with molybdenum. It is known for its high-temperature strength and resistance to deformation, making it useful in aerospace, high-temperature furnaces, and extrusion dies.
Molybdenum-Hafnium Carbon (MHC) Alloy: MHC alloy is designed to enhance performance in high-temperature environments. It combines molybdenum with hafnium and carbon to provide superior strength and thermal stability. This alloy is particularly useful in applications requiring high heat resistance, such as in aerospace and nuclear industries.

The Manufacturing Process Of Molybdenum Alloy
Liquid phase sintering method:
Tungsten-copper or molybdenum-copper mixed powders are pressed and formed, followed by liquid phase sintering at 1300-1500°C. Materials produced by this method exhibit poor uniformity, numerous closed pores, and a density typically below 98%. However, the addition of a small amount of nickel through activated sintering, mechanical alloying, or oxide reduction methods to prepare ultrafine or nanometer powders can improve sintering activity, thus enhancing the density of tungsten-copper and molybdenum-copper alloys.
Tungsten or molybdenum skeleton infiltration method:
Tungsten or molybdenum powders are pressed and formed, sintered to form a porous tungsten or molybdenum skeleton, followed by copper infiltration. This method is suitable for tungsten-copper and molybdenum-copper products with low copper content. Compared to molybdenum-copper, tungsten-copper has advantages such as lighter weight, easier processing, comparable linear expansion coefficient, thermal conductivity, and some key mechanical properties. Although its heat resistance is inferior to tungsten-copper, it still outperforms some current heat-resistant materials, making it promising for applications.

Application of Molybdenum Alloy
For hot working die:
The aeronautics and astronautics sector mainly uses molybdenum alloys to make molds and high temperature forged engine components. Its application materials are mainly active metal carbides, strengthening molybdenum, selective element strengthening molybdenum and mechanical dispersive two-phase strengthening molybdenum alloys.
For molten metal processing:
The hot cracking of the processed materials by molybdenum in the cast aluminum plant is usually used as tzm alloy (ti – zr – mo) core and mandrel in the hot cracking part of the processed material, and the thermal cracking of the material can be avoided.
For thermal spraying:
The piston ring is thermally sprayed with molybdenum. The method is to mix molybdenum powder with the binder containing nickel (ni) and chromium (cr), and then spray the mixture on the piston with plasma.
For chemical treatment:
Molybdenum is used as electrode material in glass melting process, and the processing capacity of the traditional melting furnace can also be improved. Molybdenum is suitable for high-temperature furnace because of its high-temperature strength and thermal stability.
