Abstract
A manufacturing method for an alumina-dispersed reinforced copper alloy according to the invention is an improved method which is capable of manufacturing efficiently alumina-dispersed reinforced copper having both good electro-conductivity used for wire-manufacturing-material and good mechanical property, the manufacturing method comprises the steps of obtaining powders constituted by particles having aluminum-contained copper alloy-oxide, allowing to mill aluminum-contained copper alloy powder within the air atmosphere by milling device with mechanical-alloying-operation due to shock compression, converting aluminum into aluminum-oxide by heat-treatment of the powders within inert atmosphere, implementing reduction-treatment of the converted member within the reducing atmosphere, and executing hot extrusion the reduction-treated-material.
