COPPER ALLOY-PLASTICIZED MATERIAL FOR ELECTRONIC/ELECTRIC APPLIANCES, COMPONENT FOR ELECTRONIC/ELECTRIC APPLIANCES, AND TERMINAL

摘要

PROBLEM TO BE SOLVED: To provide a copper alloy-plasticized material for electronic/electric appliances consisting of a Cu-Ti alloy, capable of exhibiting sufficient strengths even if the Ti content thereof is low and of securing high electroconductivity and strengths, and suitable for electronic/electric components such as connectors and other terminals, relays, etc.SOLUTION: The provided material has a composition including Ti within a range of 0.5 mass% or above and 3.5 mass% or below in a state where the balance thereof consists of Cu and inevitable impurities, is manufactured by a finish rolling step of performing a finishing cold or hot roll at a rolling ratio exceeding 90% and an aging heat treatment step performed after this finish rolling step, and acquires a lamellar texture after the aging heat treatment.
