摘　　要：采用正交试验方法,研究了合金成分和热处理工艺对铜合金性能的影响。试验表明,Ni和Si元素的质量比对合金硬度和电导率的影响非常大。当二者质量比为5时,对合金电导率的影响较小,且强化效果较好。同时固溶、时效、冷锻也对性能有明显影响。试验所研制的高强高导铜合金兼有较好的力学性能和电学性能,硬度(HB)和电导率分别达到181和24.94MS/m。Effects of composition and heat treatment on properties of Cu alloy were investigated by component orthogonal testing.The results show that hardness and electric conductivity of the Cu alloy are closely related to mass ratio of Ni to Si.With Ni/Si of 5,although electric conductivity of the Cu alloy is slightly changed,desirable strengthening effects on the Cu alloy can be observed.Meanwhile,the properties of the Cu alloy are also dependent on the solid solution treatment,aging treatment and cold forging.The high-strength and high conductivity Cu alloy with excellent mechanical properties and electric properties was successfully prepared,and the hardness and electric conductivity of the prepared Cu alloy reach HB181 and 14.94MS/m,respectively.
