This plating solution provides a combination good corrosion resistance and good white color, and prevents metal allergy being caused by nickel. White color copper alloy plating solution contains 30g/L to 60g/L free cyanogen, adjusted hydroxide alkali with 11 to 13 pH, soluble copper cyanide, soluble tin compound, non-ioned wetting agent as additional product of ethleneoxide, 0.1mL/L to 5mL/L interfacial activator from group of phosphate ester, 5g/L to 20g/L copper selected from copper(1) cyanide, copper(1) cyanide potassium and copper(1) cyanide natrium, 10g/L to 30g/L tin, 0.1g/L to 5g/L soluble zinc, 0.01g/L to 0.5g/L soluble lead, and 1g/L to 50g/L ammonia.
