Abstract: 
High-strength conductive cu alloys play an essential role in high-speed railways, 5G networks, and power transmission. The compound precipitates of alloying elements such as Cr, Zr, Fe, and Si in cu alloys significantly regulate the microstructure and properties of these alloys. They can ensure that the alloys have high strength without damaging conductivity seriously, which is usually a difficult problem in the development of cu alloys. This paper systematically expounds on the microstructure and concerned factors of compound precipitates in high-strength conductive cu alloys such as Cu-Cr-Zr, Cu-Zr, Cu-Ni-Si, and Cu-Fe-P. In particular, factors affecting the precipitates are summarized from the perspectives of composition and process to guide the regulation of properties. Some new, promising, high-performance cu alloys, including Cu-Co-Si, Cu-Co-Ti, and Cu-Fe-Ti, are described. Finally, we look at the research prospects for precipitation-strengthened cu alloys.
