铜系材料注射成形研究进展

Research Progress of Metal Injection Molding in Copper-based Materials

微电子行业的迅速兴起,对铜系材料提出了更高的要求。铜系材料部件的小型化、复杂化使得金属粉末注射成形工艺得到了越来越广泛的重视。介绍了金属粉末注射成形工艺及其应用,从纯铜、铜合金、铜复合材料3个方面阐述了金属粉末注射成形工艺的国内外发展近况。

As the rapid rise of the microelectronics industry, higher requirements are put forward for the copper-based materials. The process of metal injection molding（MIM） is gaining increasing attention because of the more and more small and complex of the copper-based materials parts. The process andapplication of metal injection molding are introduced, then the research status and progress of metal injection molding are reviewed in the sequence of pure copper, copper alloys and copper composites.
