Diameter 15mm Molybdenum Copper Alloy Heat Sink Rod MoCu30
1. Description of Diameter 15mm Molybdenum Copper Alloy Heat Sink Rod MoCu30:
Molybdenum copper alloy is a composite material of molybdenum and copper, its properties are similar to tungsten copper, and it also has adjustable thermal expansion coefficient and thermal conductivity. Similar to the material of tungsten copper (WuCu) heat sink material, the thermal expansion coefficient of customized different molybdenum copper (MoCu) heat sink material (molybdenum copper sheet) can also be obtained by adjusting the composition ratio of molybdenum, because molybdenum copper (MoCu) heat sink The material is much lighter than the tungsten copper (WuCu) heat sink material, Because molybdenum copper has a far lower density than tungsten copper, it is more suited for usage in the aircraft industry and other industries. High purity, uniformity of structure, and superior performance characterize the product. Since the Mo-Cu material used does not add any binder, the material has a high thermal conductivity, and the thermal expansion rate matches the ceramic materials and semiconductor materials used in the electronic sector, with cost reductions achieved through Mo-Cu stamping, mass production, and high-performance machining. Compared with molybdenum, molybdenum-copper material is more resistant to ablation, has more plasticity and machinability, and can be used as high-temperature components for rockets and missiles that use slightly lower temperatures, and can also replace molybdenum as a component in other weapons. High electrical and thermal conductivity materials are necessary for conductive and heat-dissipating components in high-power integrated circuits and microwave integrated devices, while also taking vacuum performance, heat resistance, and thermal expansion coefficient into mind. Molybdenum copper is the favored material since its qualities satisfy these specifications.
