Document Type and Number:
WIPO Patent Application WO/2011/125558
Kind Code:
A1
Abstract:
Disclosed is a Cu-Ni-Si alloy strip which contains 0.8-4.6 mass% Ni and 0.3-1.6 mass% Si and may contain one or more optional elements selected from Sn, Zn, Fe, Co, Cr, Mg, and Mn in a total amount of 2.0 mass% or less, and in which the number of shear bands in the surface layer is up to 1.0 time the number of shear bands in the sheet-thickness center part. The alloy strip has high strength and has an excellent appearance after being bent. Preferably, the number of shear bands in the surface layer is 10 or less per 10,000 µm2, and the number of 1-10 µm precipitate particles in the surface layer is 1.0×102 or less per mm2, the number of 1-10 µm precipitate particles in the surface layer being up to 1.0 time the number thereof in the center part.
