The invention discloses a preparation process for improving hardness and conductivity of a Cu-Cr-Zr alloy, and relates to the technical field of copper alloy processing. The preparation process comprises the following steps: carrying out vacuum casting, hot forging treatment and aging treatment on an alloy; the alloy comprises the following components in percentage by mass: 0.50%-1.20% of Cr, 0.08%-0.25% of Zr, 0.01%-0.10% of Nb and the balance of Cu. The alloy prepared by the preparation process has high strength and high conductivity at the same time. The preparation process is simple in flow and easy to operate and implement, the production cost is reduced on the premise that the preparation process of the alloy is shortened, and industrial production and popularization are easy. 本发明公开了一种改善Cu-Cr-Zr系合金硬度和导电率的制备工艺，涉及铜合金加工技术领域。该制备工艺包括对合金进行真空熔铸、热锻处理和时效处理；按质量分数计，合金的成分为0.50％-1.20％的Cr，0.08％-0.25％的Zr，0.01％-0.10％的Nb和余量Cu；经该制备工艺制得的合金同时具有高的强度和高的导电率。本发明的制备工艺流程简单，易于操作实施，在缩短了合金的制备过程的前提下，降低了生产成本，易于工业化生产和推广。
