Embodiment 1
[0066] A kind of 2J85T hysteresis alloy, its chemical composition comprises by weight:
[0067] 22%≤Cr≤26%;
[0068] Specifically, within the above range, the addition of chromium can expand the α phase region, and when the chromium is ≥ 26%, it will significantly deteriorate Bm and Br, and the low chromium will reduce the precipitation power of the amplitude modulation phase, which is beneficial to the reduction of Hc adjustment and the improvement of Hc temperature stability.
[0069] 8%≤cobalt Co≤15%;
[0070] Specifically, within the above range, cobalt is added to expand the γ-phase region, increase the amplitude-modulated phase precipitation kinetics, and increase Hc. Excessively high cobalt content will easily deteriorate Bm and Br.
[0071] Tungsten W≤3.0%
[0072] Specifically, within the above range, the addition of tungsten-substituted chromium will not reduce the α-phase region, and at the same time reduce the precipitation kinetics of the amplitude-modulated pha...
