Abstract: The invention relates to the technical field of amorphous soft magnetic material, specifically relating to the field of Fe—Co based amorphous soft magnetic alloy and preparation method thereof. The Fe—Co based amorphous soft magnetic alloy provided in the invention has chemical composition of FeaCobSicBdCue, which possesses merits of highly-saturated magnetic induction, outstanding soft magnetic property and great amorphous forming ability at the same time; the embodiment of Fe—Co based amorphous soft magnetic alloy disclosed in the invention has indicated that its saturation magnetic induction is 1.79˜1.86 T, coercivity 1.4˜4.3 A/m, and permeability 8000˜14000; the invention has advantages of easy treatment process, low annealing temperature, which reduces process cost remarkably and economizes energy, thus having great application prospect.

Abstract: The present disclosure relates to the field of electronic communications, and discloses a housing, a preparation method therefor, and use thereof. The housing includes a metal anodic oxide layer (5) and a resin film layer (3) adhering to a first surface of the metal anodic oxide layer (5). The metal anodic oxide layer (5) and the resin film layer (3) form an integrated structure. The preparation method includes: performing anode oxidization treatment on a metal substrate (1), and then successively performing injection molding and etching.
