Features of Moly high thermal conductivity molybdenum per kg Molybdenum TZM high temperature Molybdenum bar
Physical Characteristics
Particle Size: Ranging from nanometers to hundreds of micrometers, the size distribution significantly influences the powder’s flowability, packing density, and sintering behavior.
Shape: Particles can be spherical, irregular, flake-like, or dendritic, each shape affecting the final product’s mechanical properties and surface finish.
Purity: Depending on the production method, metal powders can achieve high levels of purity, critical for applications like electronics and aerospace where impurities can degrade performance.
Density: While less dense than their solid counterparts due to the presence of air between particles, metal powders can be densely packed during processing to approach the density of the solid metal.
Chemical Properties
Reactivity: Some metal powders, particularly aluminum and titanium, are highly reactive with air and moisture, necessitating careful handling and storage under inert atmospheres or vacuum.
Oxidation: Exposure to air can lead to surface oxidation, forming a passive layer that affects sintering and other processes. This can be managed through surface treatment or use of protective atmospheres.

Parameters of Moly high thermal conductivity molybdenum per kg Molybdenum TZM high temperature Molybdenum bar
Molybdenum, a chemical element with the symbol Mo and atomic number 42, is a silvery-gray metal known for its exceptional properties, particularly in high-temperature applications. One of its key characteristics is its high thermal conductivity, which makes it an ideal material for various engineering and industrial uses where heat transfer is critical.
Molybdenum TZM (Tungsten-Zirconium-Molybdenum) is a specific type of molybdenum that stands out due to its superior thermal properties. It is a wrought alloy, meaning it has been processed through forging or rolling, resulting in a refined microstructure that enhances its strength and stability at elevated temperatures. The “TZ” in TZM refers to the presence of tungsten and zirconium, which significantly improve the material’s creep resistance and oxidation resistance, making it suitable for demanding environments like jet engines, gas turbines, and nuclear reactors.
The high thermal conductivity of Molybdenum TZM allows it to dissipate heat efficiently, preventing overheating and maintaining optimal operating conditions. This property is crucial in components like heat exchangers, bearings, and electrical contacts, where efficient cooling is vital to prevent failure. With a thermal conductivity value around 150-200 W/m·K, it outperforms many other metals commonly used in high-temperature applications, such as stainless steel and aluminum.
In addition to its thermal conductivity, Molybdenum TZM exhibits excellent mechanical strength, with a tensile strength of around 1000 MPa and a yield strength of 750 MPa. Its high melting point, above 2623°C (4753°F), ensures its durability even under severe heating conditions. The alloy also possesses good machinability, allowing for precise fabrication into bars, plates, and shapes.
Molybdenum bars made from TZM come in various sizes and dimensions, with lengths typically ranging from a few centimeters to several meters, and diameters adapted to meet specific application requirements. These bars can be customized to have different surface finishes, such as polished or ground, for improved aesthetics or to enhance frictional properties.
In summary, Molybdenum TZM is a high-performance material characterized by its extraordinary thermal conductivity, excellent mechanical properties, and resistance to elevated temperatures. Its versatility makes it a popular choice for applications requiring reliable heat dissipation, strength, and stability, such as aerospace, power generation, and chemical processing industries. The availability of Molybdenum TZM bars in customizable sizes and finishes ensures that engineers and manufacturers can leverage this material to optimize their designs and meet the stringent demands of modern technology.
