Molybdenum, MoK, MoLa and TZM

Pure Molybdenum 

Molybdenum exhibits a high melting point and excellent thermal stability. Its properties can be varied by suitable alloy compositions and production processes. Pure and alloyed molybdenum is used in various applications such as electronics, aerospace, medical, and chemical processing industries. It is also used in the construction of high-temperature furnace components, and as a catalyst in the petroleum industry. In addition, molybdenum is used to make alloys with other metals, such as steel, to enhance their strength and corrosion resistance.                                                

 As a pure metal, molybdenum exhibits the following properties: 

High melting point of 2610 °C (2883K) 

Low thermal expansion 

High strength at high temperatures 

High electrical conductivity 

High thermal conductivity 

Good corrosion resistance 

Recrystallization temperature between 850 °C and 1000 °C (1123K and 1273K) Pure molybdenum is often used in specialized applications, such as in the production of electrical contacts and vacuum furnace parts. Alloyed molybdenum is more commonly used in a wider range of applications due to its enhanced mechanical and physical properties

Doped Molybdenum

Doped molybdenum, with trace amounts of elements such as aluminium, potassium, and silicate, is primarily produced in the form of rod and wire. The combination of doping and highly directional deformation leads to a longitudinal grain structure that increases the recrystallization temperature, improves high-temperature sag resistance, and enhances corrosion resistance against molten metals. Doped molybdenum wire is commonly used for evaporation coils and furnace elements, and doped molybdenum rods can also be used as lamp electrodes and stationary anodes for X-ray diagnostics. In addition, doped molybdenum is often used as a single or multiple-stranded wire for its improved high-temperature properties and corrosion resistance.

Molybdenum lanthanum 

Molybdenum lanthanum (MoLa) is a refractory metal alloy that combines the properties of molybdenum and lanthanum. MoLa exhibits a high melting point and excellent thermal stability, similar to pure molybdenum. However, the addition of lanthanum can improve the strength and ductility of the alloy, making it easier to process and work with. MoLa is used in various high-temperature and high-strength applications, such as in the aerospace and chemical processing industries. It is also used in the construction of furnace components, and as a catalyst in the petroleum industry. The combination of molybdenum and lanthanum creates an alloy with enhanced mechanical and physical properties, making it a suitable choice for a wide range of applications.

TZM 

TZM, or molybdenum-titanium-zirconium alloy, is a high-strength, low-expansion refractory metal. It is made by adding small amounts of titanium and zirconium to pure molybdenum, resulting in enhanced strength, toughness, and ductility at high temperatures. TZM is commonly used in applications that require high temperature stability, such as in the aerospace and defense industries, as well as in the production of furnace parts and electrical contacts. TZM also has a high melting point, good electrical conductivity, and excellent corrosion resistance. Its low coefficient of thermal expansion makes it ideal for use in precision components that need to maintain their dimensional stability under varying temperatures. TZM is available in a variety of forms, including sheets, plates, rods, and wires, and can be fabricated into custom shapes and sizes for specific applications.
