Uses Of Molybdenum And Molybdenum Alloys

Because Molybdenum and Molybdenum alloys exhibit high-temperature performance, elevated thermal conductivity and a low coefficient of thermal expansion, they are frequently employed in high-technology applications and other fields. This article examines the applications of molybdenum and molybdenum alloys.

Applications of Molybdenum and Molybdenum Alloys

1. The utilisation of molybdenum and molybdenum alloys in the iron and steel industry

When added as an alloying element in steel, molybdenum increases strength, particularly under high-temperature conditions, and improves toughness. It also enhances resistance to corrosion in acid–base solutions and liquid metals. Additionally, it improves wear resistance as well as hardenability, weldability and heat resistance.

Molybdenum forms carbides under standard conditions. It does not oxidise during steel production. It can be used either alone or in combination with other alloying elements.

Molybdenum is combined with chromium, nickel, manganese and silicon to produce various types of stainless steel, tool steel, high‐speed steel and alloyed steel.

2. The utilisation of molybdenum and molybdenum alloys in electronics and electrical engineering

Molybdenum exhibits good electrical conductivity and high temperature resistance. Its coefficient of thermal expansion closely approximates that of glass. Consequently, it is frequently used for the filament core wire, lead-in wire, support rod and other components of the spiral filament in incandescent lamps, as well as grid and anode support materials in vacuum tubes.

In addition to the use of pure molybdenum in modern electronics manufacturing, Mo–Re alloys are utilised as structural materials for vacuum tubes and specialised incandescent lamps. Moreover, Mo-50Re and TZM alloys are employed as structural components in thermionic cathodes within high-performance microwave tubes and millimetre-wave tubes.

3. The utilisation of molybdenum and molybdenum alloys in automotive coating

Molybdenum has a melting point of up to 2620 °C. It demonstrates high performance at elevated temperatures, resistance to corrosion and strong adhesion to steel. Consequently, it is the principal material for thermal spraying during the manufacture of automotive parts.

Thermal spraying increases the operational performance of piston rings, synchronising rings, rocker arms and other components. It is also applied for the repair of worn crankshafts, rollers, shafts and other mechanical parts.

4. The utilisation of molybdenum and molybdenum alloys in high-temperature components

Molybdenum is characterised by high purity, effective high-temperature performance and low vapour pressure. Consequently, it is frequently employed in the production of heating elements and construction materials for high-temperature furnaces. Molybdenum exhibits good ablation resistance in molten quartz. It is commonly used as an electrode for excitation and melting in the glass industry, and its service life may exceed 1 year.

In addition to its use as an electrode, molybdenum is used as a high-temperature structural material for glass melting, for example in guide grooves and tubes. Its use in place of platinum in the fibre drawing furnace reduces production costs considerably.

5. The utilisation of molybdenum and molybdenum alloys in oil extraction

Molybdenum is not only used in drill pipes for oil and gas fields, but it is also frequently combined with Cobalt andNickel as a catalyst in the pretreatment stage of petroleum refining.

Furthermore, molybdenum and its alloys are applied in sectors such as the nuclear industry, aerospace and environmental protection.
