Provided is a Cu-Fe-P alloy having high bending properties and high bending strength. A copper alloy containing Fe: 0.01 to 1.0%, P: 0.01 to 0.4%, and Mg: 0.1 to 1.0% by mass, respectively, consisting of residual copper and unavoidable impurities, which is extracted and separated by a specific extraction residue method. The copper alloy of which the size of Mg oxide, crystallized substance, and precipitate in a copper alloy was controlled so that the ratio with respect to Mg content in the said copper alloy of the amount of Mg by a specific measuring method in a residue is 60% or less, and high bending strength and excellent bending Combines processability |
