The invention discloses a preparation and processing method of a high-strength and high-conductivity copper alloy strip, which belongs to the technical field of metal material preparation and processing. The temperature-controlled casting continuous casting technology is used to produce copper alloy strips with excellent surface quality, compact structure, and columnar crystal structure with high orientation along the continuous casting direction, eliminating the homogenization annealing and solution treatment processes, and directly repeating a single pass Large-deformation cold rolling and aging treatment can obtain high-quality and high-performance copper alloy strips with excellent mechanical properties and electrical conductivity. The advantage of the present invention is that the preparation and processing process of the copper alloy strip is short, can promote the precipitation phase of the copper alloy strip to be fine, dispersed and multi-scale mixing uniformly distributed and more fully analyzed, reducing the solid solution of alloy elements in the matrix, a copper alloy strip with a continuous fiber strip-like structure along the length direction and excellent overall performance is obtained.
