  • COPPER ALLOY WITH HIGH STRENGTH AND EXCELLENT PROCESSABILITY IN BENDING AND PROCESS FOR PRODUCING COPPER ALLOY SHEET
    Publication number: 20120175026
    Abstract: The present invention provides a Cu—Fe—P alloy which has a high strength, high conductivity and superior bending workability. The copper alloy comprises 0.01 to 1.0% Fe, 0.01 to 0.4% P, 0.1 to 1.0% Mg, and the remainder Cu and unavoidable impurities. The size of oxides and precipitates including Mg in the copper alloy is controlled so that the ratio of the amount of Mg measured by a specified measurement method in the extracted residue by a specified extracted residue method to the Mg content in said copper alloy is 60% or less, thus endowing the alloy with a high strength and superior bending workability.
