With the shortage of copper resources, bimetal matrix composites partly replacing copper with steel have high economic value. To combine high thermal conductivity of copper with high strength of stainless steel, this paper successfully prepared T1 copper/316L stainless steel composites by single-pass cold rolling. Effects of annealing temperature on the microstructure and properties of T1 Cu/316L stainless steel composites were studied by scanning electron microscopy, hardness tests, tensile tests, tensile shear tests and electrical conductivity tests. Results showed that annealing can eliminate interface defects and improve interface structure. With the increase of annealing temperature, hardness and strength of copper/stainless steel composite materials gradually decreased, while elongation gradually increased, and electrical conductivity improved. After annealing at 700 ℃ for 2 h, excellent comprehensive properties can be obtained, with a yield strength of 539 MPa, a tensile strength of 689 MPa, an elongation of 33%, a shear strength of 191 MPa, and an electrical conductivity of 54.9%IACS.
