<p>A Cu-Fe-P alloy which combines enhanced strength and enhanced electrical conductivity with excellent processability in bending. The copper alloy comprises 0.01-1.0% iron, 0.01-0.4% phosphorus, 0.1-1.0% magnesium, and copper and unavoidable impurities as the remainder. In the copper alloy, the sizes of the oxide, crystals, and precipitate of magnesium contained in the copper alloy have been regulated so that the amount of magnesium which is contained in an extraction residue resulting from extraction/separation by a specific extraction residue method and is determined by a specific determination method is 60% or smaller based on the amount of magnesium contained in the copper alloy. This copper alloy can hence combine high strength with excellent processability in bending.</p> |
