The present invention pertains to a copper alloy for electrical and electronic equipment, a copper alloy thin sheet for electrical and electronic equipment, and a conductive part and terminal for electrical and electronic equipment. The copper alloy for electrical and electronic equipment contains more than 2.0 mass% but less than 23.0 mass% of zinc, 0.10 mass% to 0.90 mass% of tin, 0.05 mass% to less than 1.00 mass% of nickel, 0.001 mass% to less than 0.100 mass% of iron, and 0.005 mass% to 0.100 mass% of phosphorus, with the remainder comprising copper and unavoidable impurities. The copper alloy satisfies 0.002 ≤ Fe/Ni < 1.500, 3.0 < (Ni + Fe)/P < 100.0, and 0.10 < Sn/(Ni + Fe) < 5.00 in terms of atomic ratios. The content of hydrogen is not more than 10 mass ppm, the content of oxygen is not more than 100 mass ppm, the content of sulfur is not more than 50 mass ppm, and the content of carbon is not more than 10 mass ppm. |
