TERMINAL PLATING MATERIAL, AND TERMINAL, TERMINAL-EQUIPPED ELECTRIC WIRE AND WIRE HARNESS USING THE SAME

摘要

A terminal plating material includes a metal substrate, and a silver-tin alloy plating layer containing a silver-tin alloy, arranged on the metal substrate. The silver-tin alloy plating layer contains an intermetallic compound of silver and tin, the Vickers hardness of the surface of the silver-tin alloy plating layer in the terminal plating material is 250 Hv or more, and the surface roughness of the silver-tin alloy plating layer is 0.60 μmRa or less. Further, a terminal is formed from the terminal plating material. A terminal-equipped electric wire includes the terminal. A wire harness includes the terminal-equipped electric wire.
