I. Definition and Impact of the Density of Sintered Molybdenum Rods

The density of sintered molybdenum rods refers to the actual density of the molybdenum powder formed during the hot-pressing manufacturing process. This density has a significant impact on the properties of molybdenum rods, including hardness, wear resistance, and corrosion resistance. Specifically, molybdenum rods with higher density tend to have higher hardness and wear resistance, as the higher density indicates a tighter arrangement of particles within the material, thus enhancing the overall strength of the material.

II. Physical Properties of Sintered Molybdenum Rods

High Melting Point: The melting point of molybdenum rods is as high as 2610°C, one of the highest among all metals. This allows molybdenum rods to maintain stability and strength under extremely high temperatures, making them widely applicable in high-temperature environments.

Low Coefficient of Thermal Expansion: Molybdenum rods have a very small coefficient of linear expansion and a low thermal expansion coefficient. This ensures that molybdenum rods maintain their shape and size stability at high temperatures, which is crucial for the manufacturing of high-temperature equipment and components.

Excellent Thermal Conductivity: Molybdenum rods possess good thermal conductivity, enabling them to efficiently transfer heat from one end to the other. This characteristic improves the thermal stability of molybdenum rods under high-temperature conditions and enhances their efficiency as a heat conduction material.
