Molybdenum Rod

Molybdenum Rod (Mo) – Properties, Advantages and Applications

Molybdenum rods are high-quality semi-finished metal products made from the refractory transition metal molybdenum (Mo), which has the atomic number 42. They are characterized by high temperature resistance, good mechanical strength and excellent thermal conductivity. Due to these properties, molybdenum rods are used in numerous industries, particularly in mechanical engineering, high-temperature technology, the electronics industry and metalworking.

Molybdenum is a silvery-gray metal that is primarily extracted from the mineral molybdenite (MoS₂). Thanks to its distinctive physical properties, it is suitable for manufacturing technical components that must withstand high thermal and mechanical loads.

Properties of Molybdenum Rods

Molybdenum has a density of approximately 10.22 g/cm³ and a melting point of around 2623 °C. The metal offers high strength at elevated temperatures and a low coefficient of thermal expansion. As a result, molybdenum rods exhibit good dimensional and shape stability under suitable operating conditions.

The rods can be machined using various mechanical processes such as turning, milling and grinding. Their machinability depends on the material condition and the specific manufacturing conditions.

Molybdenum can oxidize at high temperatures in oxygen-containing atmospheres. Therefore, vacuum or protective gas environments are frequently used for high-temperature applications.

Industrial Uses

Molybdenum rods are used to manufacture furnace components, electrodes, supports and other technical components. In high-temperature technology, they serve as a starting material for components exposed to high temperatures.

In the electronics industry, molybdenum rods are used for specialized electrical contacts and electrodes. They are also used in mechanical engineering, vacuum technology and the manufacture of components for industrial equipment.
