Description of Mo-Cu Alloy Rod

Molybdenum-copper material, like tungsten-copper material, is a pseudo-alloy composed of two mutually immiscible metal phases. Therefore, this material should have the characteristics of both constituent metals, and can learn from each other to obtain good comprehensive performance.

Mo-Cu Alloy rod combines the high thermal conductivity of copper and the low thermal expansion of molybdenum. The most typical molybdenum-copper ratios are 70/30 and 80/20. Generally, the ratios from Mo90Cu10 to Mo60Cu40 can be produced by our company.

Mo-Cu Alloy rod has many advantages, such as high electrical and thermal conductivity, convenient processing, good plasticity, good high-temperature stability, and excellent arc ablation resistance.

Mo-Cu Alloy rod is the material of choice for devices such as heat sinks, microelectronic components, and aerospace accessories. In the actual application process, by adjusting the range of composite ratio, the thermal expansion coefficient of molybdenum-copper alloy components, such as radiators and radiators can be matched with those of other device components, and the internal thermal stress can be reduced to significantly improve the performance of the device. functionality and reliability.

Manufacturing Process of Mo-Cu Alloy Rod

Smelting: Isostatic pressing (high-temperature sintering-copper infiltration) is adopted.
Processing: After turning, the surface shall not have defects such as holes, cracks, delamination or inclusions.
Heat treatment: Hot forging deformation, when the deformation is less than 60%, the relative density and uniformity of the rod are improved.
