Abstract (en)
A copper alloy material for an electrical/electronic equipment, containing Ni 3.3 to 5.0 mass%, having a content of Si within the range of 2.8 to 3.8 in terms of a mass ratio of Ni and Si (Ni/Si), and containing Mg 0.01 to 0.2 mass%, Sn 0.05 to 1.5 mass%, and Zn 0.2 to 1.5 mass%, with the balance of Cu and inevitable impurities, wherein when a test piece with thickness t of 0.20 mm and width w of 2.0 mm is subjected to 90° W-bending with bending radius R of 0.1 mm, no cracks occur on the test piece; and, an electrical/electronic part obtained by working the same.
