Patent ID: 11211729

Abstract:
A terminal material for a connector terminal, using a copper or copper alloy substrate is crimped to an end of wire formed from an aluminum wire material; and a terminal using this terminal material: a zinc layer 4 that is formed of zinc or a zinc alloy and a tin layer 5 that is formed of tin or a tin alloy are sequentially laminated in this order on a substrate 2 that is formed of copper or a copper alloy: with respect to the zinc layer and the tin layer, the adhesion amount of tin contained in the whole layers is from 0.5 mg/cm2 to 7.0 mg/cm2 (inclusive) and the adhesion amount of zinc contained in the whole layers is from 0.07 mg/cm2 to 2.0 mg/cm2 (inclusive), and the content percentage of zinc in the vicinity of the surface is from 0.2% by mass to 10.0% by mass (inclusive).
