Abstract

A method of manufacturing a terminal comprising, in the following order, preparing a sheet material comprising 0.005 mass %-3.000 mass % in total of at least one element selected from Mg, Si, Cu, Zn, Mn, Ni, Cr and Zr, the balance being Al and incidental impurities, performing solution heat treatment by heating the sheet material, cold rolling the solution heat treated sheet material, forming a metal coating layer over a part of or an entirety of the cold-rolled sheet material, the metal coating layer being composed primarily of Sn, Cr, Cu, Zn, Au or Ag, or an alloy composed primarily thereof, forming a developed terminal material by punching the sheet material into a developed view geometry of a terminal, forming the developed terminal material into a terminal, and performing an aging treatment on the terminal at 150-190° C. for 60-600 minutes.

First claim

What is claimed is:

1 . A method of manufacturing a terminal, comprising, in the following order:
preparing a sheet material comprising greater than or equal to 0.005 mass % and less than or equal to 3.000 mass % in total of at least one element selected from Mg, Si, Cu, Zn, Mn, Ni, Cr and Zr, the balance being Al and incidental impurities; performing solution heat treatment by heating the sheet material; cold rolling the solution heat treated sheet material; forming a metal coating layer over a part of or an entirety of the cold-rolled sheet material, the metal coating layer being composed primarily of Sn, Cr, Cu, Zn, Au or Ag, or an alloy composed primarily thereof; forming a developed terminal material by punching the sheet material on which the metal coating layer is formed into a developed view geometry of a terminal; forming the developed terminal material into a terminal; and performing an aging treatment on the terminal under a condition of 150° C. to 190° C. for 60 to 600 minutes.

2 . The method of manufacturing a terminal according to claim 1 , further comprising forming an undercoat layer between the sheet material and the metal coating layer.

3 . A method of manufacturing a terminal, comprising, in the following order:
preparing a sheet material comprising greater than or equal to 0.005 mass % and less than or equal to 3.000 mass % in total of at least one element selected from Mg, Si, Cu, Zn, Mn, Ni, Cr and Zr, the balance being Al and incidental impurities; performing solution heat treatment by heating the sheet material; cold rolling the solution heat treated sheet material; forming a developed terminal material by punching the cold-rolled sheet material into a developed view geometry of a terminal; forming a metal coating layer over a part of or an entirety of the developed terminal material, the metal coating layer being composed of Sn, Cr, Cu, Zn, Au or Ag or an alloy composed primarily thereof; forming the developed terminal on which the metal coating layer is formed into a terminal; and performing an aging treatment on the terminal under a condition of 150° C. to 190° C. for 60 to 600 minutes.

4 . The method of manufacturing a terminal according to claim 3 , further comprising forming an undercoat layer between the sheet material and the metal coating layer.
