Title:
COPPER WITH SURFACE COATING LAYER OR COPPER ALLOY SHEET STRIPE
Document Type and Number:
Japanese Patent JP2017082307
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a copper alloy sheet stripe with surface coating layer (conductive material for connection part) maintaining low friction coefficient (low insertion force) even during repeating a plurality of times of withdrawal and excellent in minutely slide abrasion resistance.SOLUTION: There is provided a copper or copper alloy sheet stripe with a surface coating layer, which coats whole area of a Cu-Sn alloy layer, having a copper or a copper alloy sheet stripe as a base material and a ground layer consisting of one or two of Ni, Co or Fe layer, the Cu-Sn alloy layer and a Sn layer as a surface coating layer in this order, wherein average thickness of the ground layer is 0.1 to 3.0 μm, the Cu-Sn alloy layer is a η phase or a η phase and an ε phase, average thickness is 0.2 to 3.0 μm, arithmetical average height Sa of a surface thereof is 0.2 μm or less, maximum height Sz is 5.0 μm or less, average thickness of the Sn layer is 0.02 to 0.2 μm.SELECTED DRAWING: Figure 3
