Connectors for boards and modules are becoming narrower in pitch due to multipolarization and smaller because electronic 遊雅堂 キャンペーンコード 2024ices are becoming compact and multifunctional. A copper alloy strip used for electric contact materials in these small-sized connectors requires high strength and good performance to bending. Furukawa Electric improved these two conflicting features under the control of the metal structures: we have 遊雅堂 キャンペーンコード 2024eloped a new Cu-Ni-Si alloy (Colson alloy) EFTEC-820 (C64775: Cu-2.3Ni-0.65Si-0.5Zn- 0.15Sn-0.1Mg-0.15Cr). This paper reports the improved features of this alloy and our grainrefining technology that contributes to achieving these features.
