Zusammenfassung:	PROBLEM TO BE SOLVED: To improve the whisker resistance of a copper alloy material for electrical-electronic parts without damaging the advantages of the excellent press blanking properties and low friction coefficient of bright electrotinning. SOLUTION: Bright electrotinning having a plating thickness of 0.5 to 2 μm, and in which the reflectivity of the surface is
