Applications of Molybdenum and Its Alloy

With the development of science and technology, the application of molybdenum in high-tech and other fields has also been increasing. Next, let's take a look at the application of molybdenum and its alloys.

Iron and Steel Industry

Molybdenum is a good element that forms carbides and will not be oxidized during the steelmaking process. It can be used alone or together with other alloying elements. Molybdenum is used together with chromium, nickel, manganese, and silicon to produce different types of stainless steel, tool steel, high-speed steel, and alloy steel.

Electrical and Electronic Industry

Molybdenum has good electrical conductivity and high-temperature performance, especially since the thermal expansion coefficient of glass is very close, so it is widely used in the core wire, lead wire, side rod, and other parts of the spiral filament in the bulb, and used as the grid and anode support material in the electron tube.

In addition to the use of pure molybdenum in the modern electronics industry, Mo-Re alloys can be used as structural materials for electron tubes and special bulbs, and Mo-50Re and TZM alloys can also be used as structural components of thermionic cathodes in high-power microwave tubes and millimeter-wave tubes.

Car Coating

The melting point of molybdenum is as high as 2620°C, and it has good high-temperature performance and corrosion resistance and has a strong bonding force with steel. Therefore, it is the main thermal spraying material in the production of automobile parts. Thermal spray materials can significantly improve the performance of piston rings, synchronizer rings, shift forks, and other worn parts, and are also used to repair worn crankshafts, rolls, shafts, and other mechanical parts.

High-Temperature Components

Molybdenum has high purity, good high-temperature resistance, and low vapor pressure, so it is often used to make heating elements and structural materials for high-temperature furnaces. Molybdenum has good ablation resistance in molten quartz. It is often used as an electrode for energization and melting in the glass industry, and its service life can reach more than one year.
In addition to being used as an electrode, molybdenum can also be used as a high-temperature structural material for glass melting, such as guide grooves and pipes. The use of molybdenum instead of platinum on the glass fiber drawing furnace has a good effect, which greatly reduces the production cost. In addition, molybdenum and its alloys can also be used for hot isostatic pressing, heat shields, sintering steaming paint boats, etc.

Oil Exploitation

Molybdenum can not only be used in oil and gas field drilling pipelines but is also often combined with cobalt and nickel as a catalyst for petroleum refining and pretreatment, mainly for the desulfurization of petroleum, petrochemical products, and liquefied coal. Molybdenum plays an important role in petroleum cracking and reforming and is an ideal electron donor and carrier.
