Embodiment Construction
[0036] The present invention is described in further detail below with reference to the examples.
[0037] According to the composition of Table 1, the copper alloy shown in Table 1 was fuse at 1150 ° C, and a range of spots having a specification of 170 mm × 320 mm was produced. After holding the above ingot 800 ° C for 5 hours, hot rolling has a thickness of 16.5 mm, and after the hot rolling is completed, then the wire is cooled; then the milling surface makes the thickness of 15 mm, and then the thickness of 2 mm by cold rolling The board is heated to 440 ° C, then heat the plate after heat rolling, and the first time is performed; the timing is subjected to a second cold rolling, cold rolled to 0.4 mm, then thermally warmed at 400 ° C for 8 h The second aging treatment; finally cold rolling, rolling the target plate thickness 0.3 mm; after cooling, the temperature is maintained at 210 ° C for 4 hours to perform low temperature annealing to obtain a strip sample.
