Product Brief Introduction
Molybdenum is similar to Tungsten, with melting point of 2620℃(4753
), a little lower than tungsten. The elongation ability is better than Tungsten, and it is easier to make the thin wires and thin foils.
It has the lowest coefficient of thermal expansion(CTE) of any pure metals, its CTE matches well with semiconductor materials, such as, Si, GaN, GaAs,,
.

Molybdenum heating element is a type of high-temperature resistive heating component made primarily from the refractory metal molybdenum (Mo). These elements are specifically engineered for applications in industrial and laboratory furnaces where extremely high temperatures and controlled atmospheres are required.
Properties and Advantages
Molybdenum is chosen for heating elements due to its unique combination of physical and chemical properties:
Extremely High Melting Point: With a melting point of 2,623°C (4,753°F), molybdenum can operate at temperatures far exceeding those of conventional nickel-chromium (e.g., Kanthal) or iron-chromium-aluminum alloys. Typical maximum operating temperatures in hydrogen or vacuum are in the range of 1,600°C to 1,800°C (2,912°F to 3,272°F).
- Good High-Temperature Strength: It maintains excellent mechanical strength and resists sagging or deformation (creep) at elevated temperatures, ensuring dimensional stability and long service life.
- High Resistivity: Molybdenum has a favorable electrical resistivity (~5.7 μΩ·cm at 20°C), which allows it to efficiently convert electrical energy into heat.
- Low Thermal Expansion: Its coefficient of thermal expansion is relatively low, which reduces thermal stress and the risk of cracking during rapid heating or cooling cycles.
Commen Uses
The elements are manufactured in various forms-including rods, bars, U-shapes, and meshes-to fit different furnace designs and heating uniformity requirements. Their primary applications are found in:
- Vacuum furnaces for processes like sintering, brazing, and heat treatment of advanced materials.
- High-temperature research and laboratory furnaces.
- Equipment for crystal growth, such as in the production of synthetic sapphire.
