The effects of copper foil production process parameters on tensile strength and elongation of copper foil were optimized by single factor and response surface test. The results show that the optimal process conditions for the optimization of the response surface are temperature of 60 ℃, current density of 65 A/dm2, liquid flow of 55 m3/h, and the influence of each factor on tensile strength is current densi-ty> temperature > liquid flow, and the influence on elongation is temperature> current density > liquid flow, in which the interaction between temperature and current density on the tensile strength of copper foil is significant. In addition, the crystal face of copper foil (111) prepared under optimal process con-ditions has the largest diffraction intensity and a texture coefficient of 46.9％, which has an obvious preference orientation.
