Copper alloy strip material for electrical/electronic equipment and process for producing the same
Abstract:
A copper alloy strip material for electrical/electronic equipment includes a copper alloy containing 2.0 to 5.0 mass % Ni, 0.43 to 1.5 mass % Si, and a remaining component formed of Cu and an unavoidable impurity. Three types of intermetallic compounds A, B, and C comprising Ni and Si in a total amount of 50 mass % or more are contained. The intermetallic compound A has a compound diameter of 0.3 μm to 2 μm, the intermetallic compound B has a compound diameter of 0.05 μm to less than 0.3 μm, and the intermetallic compound C has a compound diameter of more than 0.001 μm to less than 0.05 μm.
