Molybdenum Copper Alloy Bar

Molybdenum copper alloy bar contains 50%-85% Molybdenum. O-Cu copper alloy composites have lower density; their thermal expansion coefficient and thermal conductivity can be adjusted to match many different materials. Molybdenum copper is a great alternative to tungsten copper for weight-sensitive applications. The combination of high-purity raw materials and high-temperature hydrogen sintering using no additives yields the highest thermal conductivity available for this composite material system.

Powder metallurgy method: high-quality molybdenum powder and oxygen-free copper powder are used, and are prepared by isostatic pressing, high-temperature sintering, and copper infiltration. This method ensures product purity and accurate ratio, fine structure, and excellent performance.
Liquid phase sintering method: After the molybdenum-copper mixed powder is pressed into shape, liquid phase sintering is performed at 1300-1500°C. This method is suitable for molybdenum-copper products with low copper content, but there are problems such as poor uniformity and many closed pores.
Skeleton infiltration method: first, press the molybdenum powder into shape and sinter it into a skeleton with a certain porosity, and then infiltrate copper. This method is suitable for molybdenum-copper products with low copper content, but the density of the material after infiltration is low, which may affect air tightness and conductivity.

High Thermal and Electrical Conductivity: Molybdenum-copper rods conduct thermal energy at 200-400 W/m·K and electricity, exhibiting efficient heat and electrical energy transfer.

Low Thermal Expansion: Molybdenum has a low thermal expansion, while copper has a higher one. The ratio of molybdenum to copper can be adjusted; an alloy comprising these two elements can be tailored to meet specific requirements.

High-Temperature Performance: The melting point of molybdenum is 2610°C, which means that this alloy will retain a degree of strength and plasticity at elevated temperatures, even after the copper it contains succumbs to melting.

Non-Magnetic: Molybdenum, along with copper, does not exhibit magnetism, and therefore, the alloy possesses good non-magnetic properties as well.

Good Machinability: The alloy can easily be shaped into more complex forms than pure molybdenum due to its softness and higher ductility.

Corrosion & Oxidation Resistance: The alloy is particularly resistant to oxidation and corrosion and does not corrode even at elevated temperatures.

Aerospace Industry: Molybdenum-copper alloy rods withstand the extremes of heat and mechanical stress, making them suitable for jet engines, rocket nozzles, and combustion chambers.

Electronics: The alloy's application includes serving as IC packaging, a heatsink, or a thermal spreader; thus, preventing government overheating.

High-Temperature Furnace Parts: The rods are used in heating elements and insulation supports for furnaces where high-temperature stability is required.

Medical Equipment: Components requiring extreme reliability and thermal conductivity, made from the alloy, are used in X-ray and other imaging devices.

Vacuum Switches & Electrodes: Due to its wear resistance and excellent conductivity, the alloy is used in electrical contacts and electrodes of vacuum switches.

Surface quality: The surface of the molybdenum-copper alloy rod is turned and must not have defects such as holes, cracks, delamination, or inclusions. Its dimensional accuracy and allowable deviation meet strict standards.
Chemical composition: The ratio of molybdenum and copper, as well as the total amount of impurity elements, is strictly controlled. For example, the copper content of MoCu15 is 15±3%, and the total amount of impurity elements is ≤0.1%.
