CU-ZR-BASED COPPER ALLOY PLATE AND PROCESS FOR MANUFACTURING SAME |
摘要 |
Provided are a Cu-Zr-based copper alloy plate which retains satisfactory mechanical strength and, at the same time, has a good balance of bending formability and bending elastic limit at a high level and a process for manufacturing the Cu-Zr-based copper alloy plate. The copper alloy plate contains 0.05% to 0.2 % by mass of Zr and a remainder including Cu and unavoidable impurities, and the average value of KAM values measured by an EBSD method using a scanning electron microscope equipped with a backscattered electron diffraction pattern system is 1.5° to 1.8°, the R/t ratio is 0.1 to 0.6 wherein R represents the minimum bending radius which does not cause a crack and t represents the thickness of the plate in a W bending test, and the bending elastic limit is 420 N/mm 2 to 520 N/mm 2 . |
