Many attempts were conducted to improve Cu–Cr alloys’ softening temperature, strength, and electrical conductivity. After homogenised treatment at 900°C for 4 h, hot rolled by 80% at 900°C, solid solution treated at 940°C for 2 h, cold rolled by 50%, and aged at 450°C for 1 h, cold rolled by 50%, and aged at 450°C for 0.5 h, the tensile strength, yield strength, microhardness, and electrical conductivity of the fabricated Cu–2Cr–1Zn alloy were 616.7, 540.1 MPa, 176.7 HV, and 71.5% IACS, respectively, with a softening temperature of 530°C. Orowan precipitation strengthening was the primary strengthening mechanism. These findings bring an effective way to improve the strength and softening temperature with a small loss of electrical conductivity.
