摘要（英）：

The invention provides a high-performance CuNiSiTiBMg-series elastic copper alloy and a preparation method of the high-performance CuNiSiTiBMg-series elastic copper alloy. The high-performance CuNiSiTiBMg-series elastic copper alloy comprises the ingredients of, in percentage by weight, 8.0-12.0% of Ni, 2.0-3.0% of Si, 0.5-2.0% of Ti, 0.02-0.5% of B, 0.2-0.3% of Mg and the balance Cu and inevitable impurities. The elastic copper alloy is reasonable in ingredient, strengthening phases in the alloy are uniformly distributed, and the high-performance CuNiSiTiBMg-series elastic copper alloy has the characteristics of being high in strength, good in plasticity, high in specific conductance and excellent in stress relaxation resistance. The preparation method of the elastic copper alloy comprises the steps of continuous casting and rolling, hot rolling, solution treatment, cold rolling, aging treatment, multiple times of pack rolling, low tempering and the like. The preparation method has the characteristics that energy is saved, consumption is lowered, the production cost is lower, and the process is simpler, and the preparation method is more suitable for industrial production.
