Abstract
The invention is a copper alloy with excellent comprehensive performance, including the following components in percentage by weight: 0.4 wt %-2.0 wt % of Ni, 0.2 wt %-2.5 wt % of Sn, 0.02 wt %-0.25 wt % of P, 0.001 wt %-0.5 wt % of Si, and the balance of Cu and unavoidable impurities. The copper alloy has a yield strength of 550 MPa or above, and an electrical conductivity of 38% IACS or above. A bending workability is as follows: the value of R/t in the GW direction is less than or equal to 1, and the value of R/t in the BW direction is less than or equal to 2; and after the copper alloy is kept at 150° C. for 1000 hours, a residual stress rate is greater than or equal to 75%, and the stress relaxation resistance is excellent.
