By means of Ni solution strengthening, a microalloying refine structure and a second phase, the high-strength and corrosion-resistant Cu-Ni alloy wire material with excellent comprehensive performance is obtained.

Description

technical field [0001] The invention relates to the technical field of nonferrous metals, in particular to a high-strength and high-conductivity copper alloy wire material and a preparation method thereof. Background technique [0002] With the rapid development of modern industry in the 21st century, the demand for high-strength, high-hardness, heat-resistant, electrically conductive, and thermally conductive copper alloys is becoming more and more urgent. This type of alloy is widely used in lead frame materials, overhead wires of high-speed electric locomotives, generator sets, etc. At present, it is required to improve the electrical conductivity of this type of material as much as possible under the premise of satisfying its service strength. But the high strength and high conductivity of copper are a pair of contradictions. The key factor affecting conductivity is impurity scattering, which must be reduced in order to obtain maximum conductivity. However, the existi...
