摘要： The present invention relates to a copper alloy in which Si used in a copper-stretching factory is employed to facilitate deoxidation, and which can be easily manufactured even when elements such as Cr, Sn or the like are contained in the alloy, and which is made of components that can be molten and casted in the atmosphere, in a non-oxidizing atmosphere, or in a reducing atmosphere, so as to provide the copper alloy with high conductivity and high workability without negatively affecting the tensile strength of the copper alloy, and in which a high-temperature solution treatment is eliminated in manufacturing materials for the copper alloy, wherein the high-temperature solution treatment might otherwise be performed after the completion of a hot-rolling process for fully melting Cr into a Cu matrix, thereby shortening processes and reducing manufacturing costs. The copper alloy of the present invention having high tensile strength, high workability and high conductivity, has 100 wt % consisting of 0.2 to 0.4 wt % of Cr, 0.05 to 0.15 wt % of Sn, 0.05 to 0.15 wt % of Zn, 0.01 to 0.30 wt% of Mg, 0.03 to 0.07 wt% of Si, with the remainder being Cu and inevitable impurities. In addition, a method for manufacturing the copper alloy according to the present invention comprises the following steps: obtaining a molten metal of the above-described composition; obtaining an ingot; heating the ingot at a temperature of 900-1000°C to perform a hot-rolling process; performing a cold-rolling process; performing a first aging process at a temperature of 400-500°C for 2 to 8 hours; performing a cold-rolling process; and performing a second aging process at a temperature of 370-450°C for 2 to 8 hours.
