A dezincification-resistant copper alloy and a method for producing a product containing the same are proposed by the present invention. The dezincification-resistant alloy of the present invention contains 59.5 to 64 wt % of copper (Cu); 0.1 to 0.5 wt % of bismuth (Bi); 0.08 to 0.16 wt % of arsenic (As); 5 to 15 ppm of boron (B); 0.3 to 1.5 wt % of tin (Sn); 0.1 to 0.7 wt % of zirconium (Zr); less than 0.05 wt % of lead (Pb); and zinc (Zn) in balance. The dezincification-resistant copper alloy of the present invention has excellent casting properties, good toughness and machinability, and can be corrosion-resistant. Thus, the alloy can reduce dezincification on the surfaces.
