Abstract
A plated material for connectors, having superior insertion and withdrawal properties, comprises an intermediate layer consisting of Ni alloy plating having a Vickers hardness of 450 to 750 Hv and a thickness of 0.3 to 2 &mgr;m provided on a base metal consisting of Cu or Cu alloy, a reflowed Sn or Sn alloy plated surface layer provided thereon, and an alloy layer consisting primarily of Sn—Ni and having a thickness of 0.05 to 2 &mgr;m formed by diffusion between the intermediate layer and the surface layer, in which average grain size of said Sn—Ni compound is 0.05 to 1 &mgr;m.
