PROBLEM TO BE SOLVED: To provide a Cu-Fe-based alloy for an electromagnetic shielding material with high electromagnetic shielding effects to electromagnetic waves with ≥5 MHz frequency.SOLUTION: The Cu-Fe-based alloy contains 10.0-50.0 mass% of Fe, 0.001-5.0 mass% total of one or two of Ni and Co, and ≥10 ppm of C, which is a copper alloy where Fe-based secondary phase is crystallized and precipitated in the Cu mother phase. It may further contain 0.005-2.0 mass% total of one or two or more of P, Si, Ti, Mg, Ca, Zr, Cr, Al and B, 0.005-5.0 mass% of Zn, and 0.001-5.0 mass% total of one or two or more of Ag, Sn, In, Mn, Au and Pt. |
