Abstract:

Cu-Ni-Si alloys have become an indispensable key material in fields such as electronic information, new energy vehicles, and aerospace due to their excellent electrical conductivity, strength, and stress relaxation resistance. However, there are still many challenges in optimizing the composition design, improving the preparation and processing technology, and exploring the mechanism for synergistic improvement of comprehensive performance of high-performance Cu-Ni-Si alloys. Therefore, this article analyzes and summarizes the scientific research achievements of Cu-Ni-Si alloys in recent years, deeply explores the influence and mechanism of the types, contents, and mass ratios of alloy elements, as well as thermomechanical treatment process on their conductivity, strength, and stress relaxation resistance, and looks forward to their future research directions.
