摘要： A composite soft magnetic material includes the following components: 67.9 to 95.54 wt % of FeSiCr, 0.1 to 0.3 wt % of TiO2, 0.15 to 0.75 wt % of SiO2, 0.1 to 0.5 wt % of Mn3O4, 0.1 to 0.5 wt % of ZnO, 3.4 to 25.9 wt % of BaO, 0.4 to 3 wt % of B2O3, 0.2 to 0.85 wt % of CaO, and 0.01 to 0.3 wt % of CuO. The composite soft magnetic material has high initial permeability and high Bs, excellent temperature stability, and low temperature coefficient.
