The invention relates to the technical field of non-ferrous metal processing, in particular to an ultra-high-strength, stress-relaxation-resistant, excellent bending and forming conductive copper alloy, and a preparation method and application thereof. The conductive copper alloy provided by the present invention regulates the composition and microstructure of the copper-based elastic alloy through the synergistic effect of alloying elements, controls the growth of the high temperature resistant phase and the precipitation of the discontinuous precipitated phase, and obtains a variety of micro-nano-sized structures The precipitated phases are dispersed and distributed in the matrix. At the same time, the type and composition of the texture are adjusted on the basis of the above microstructure through the synergistic mechanism of a variety of alloying elements. The resulting conductive copper alloy has ultra-high strength and stress resistance. The excellent performance of relaxation and excellent bending and forming, fully meet the requirements of the use of copper alloy materials for high-end electronic components in the fields of aerospace, 5G communications, smart terminals and other fields.
