Document Type and Number:
WIPO Patent Application WO/2017/195768
Kind Code:
A1
Abstract:
Provided is an electrochemical corrosion-proof terminal material that uses a copper or copper alloy base as the terminal which is crimped to the end of an electrical wire formed from an aluminum wire material. An intermediate zinc layer 4 formed from zinc or a zinc alloy and a tin layer 5 formed from tin or a tin alloy are layered in that order on a base 2 formed from copper or a copper alloy. Preferably, the intermediate zinc layer 4 has a thickness of 0.1-5.0 µm and a zinc concentration of 5 mass% or greater, the zinc concentration of the tin layer 5 is 0.4-15 mass%, and the crystal grain size of the tin layer 5 is 0.1-3.0 µm.
