Molybdenum is a refractory metal that combines high-temperature mechanical strength, good thermal conductivity, and excellent corrosion resistance. It is used in many industrial sectors, ranging from metallurgy to electronics and aerospace.

What is molybdenum?

Molybdenum (symbol Mo, atomic number 42) is a silvery-gray metal with a melting point of 2,623 °C. Classified as a refractory metal, it is distinguished by its combination of mechanical strength, thermal conductivity, and chemical stability.

This metal has many advantages:

high mechanical strength at high temperatures
good thermal conductivity
excellent resistance to corrosion by molten metals
a low coefficient of thermal expansion

The most common alloys are TZM (Mo-Ti-Zr), MoLa (molybdenum-lanthanum), and Mo-Re (molybdenum-rhenium), each optimized for specific applications.

The Properties of Molybdenum

High-Temperature Resistance

Molybdenum retains its mechanical properties at temperatures exceeding 1,500 °C. The TZM alloy pushes this limit even further through the addition of titanium and zirconium, making it suitable for the most demanding applications.

Thermal Conductivity

Molybdenum offers thermal conductivity superior to that of many special steels, making it the material of choice for heat exchangers, heat sinks, and furnace electrodes.

Resistance to molten metals

Molybdenum is remarkably resistant to corrosion by molten metals (zinc, aluminum, glass). It is widely used in the manufacture of electrodes, mandrels, and components for the glass and metallurgical industries.
