摘要: A pin terminal includes a bar-like base material and a plating layer covering a predetermined region of the base material. A constituent material of the base material is pure copper or a copper alloy. The plating layer includes a tin-based layer made of metal containing tin. One end side of the base material includes a tip covering portion covering an entire region in a circumferential direction of the base material. The tin-based layer includes the tip covering portion. The tip covering portion includes a thin film portion and a thick film portion at positions different in the circumferential direction of the base material. The thin film portion is provided in contact with the base material. The number of whiskers present on a surface of the thin film portion is 15 or less in a square visual field having one side length of 0.35 mm.

A constituent material of the base material is pure copper or a copper alloy. The plating layer includes a tin-based layer made of metal containing tin. One end side of the base material includes a tip covering portion. The tin-based layer includes the tip covering portion. The tip covering portion covers an entire region in a circumferential direction on the one end side of the base material. A difference (t1−t2) between a maximum value t1 and a minimum value t2 of a thickness of the tip covering portion measured at a measurement location set at a spot of 1 mm from one end of the pin terminal along a longitudinal direction of the pin terminal is 0.20 μm or more.

摘要: Provided are a metal material and a connection terminal, the metal material being capable of suppressing an increase in the friction coefficient on the surface of a Sn-containing metal layer even without using Ag. This metal material 1 has a base material 15 and a surface layer 10 with which the surface of base material 15 is covered, wherein the surface layer 10 contains Sn and In, and at least In is present on the outermost surface thereof. In addition, this connection terminal is composed of said metal material 1, and the surface layer 10 is formed on the surface of the base material 15, in at least a contact section making electrical contact with the counterpart conductive member.

摘要: The electrical contact material includes a base material, a coating layer provided on a surface of the base material, and an oxide layer provided on a surface of the coating layer. The base material contains Cu. The coating layer contains Zn, Cu, and Sn. The oxide layer is constituted by an oxide containing Zn, Cu, and Sn. When a spherical indenter with a radius of 1 mm is linearly slid against the oxide layer with an applied load of 1 N, a sliding speed of 100 μm/sec, a stroke of 50 μm, and 10 reciprocation cycles, the largest contact resistance measured after the first to 10th reciprocation cycles is not larger than 5 mΩ.
