Magnetically soft alloy

Abstract

The invention relates to a magnetically soft alloy, which is the basic material of FeCOMSiBTi, wherein each component comprises by atom percent (at %): 25-30 percent of cobalt, 3-5 percent of M, 8-12 percent of silicon, 10-15 percent of boron, 5-8 percent of titanium and 1-3 percent of scandium, and the rest percent if iron and few amount of inevitable impurities; and the combination is M copper and one or more of niobium, molybdenum, vanadium, and zirconium.

Description

technical field [0001] The invention belongs to the field of functional materials, in particular to a soft magnetic alloy. Background technique [0002] In the prior art, soft magnetic materials are used to produce high-frequency transformers, magnetic heads and other products that need to utilize the characteristics of soft magnetic materials. Soft magnetic materials refer to magnetic materials that have demagnetization properties compared with permanent magnetic materials. At present, the production of main soft magnetic materials is basically made of ferrite materials. The main characteristics of this type of ferrite materials are high resistivity and small high-frequency eddy current loss. However, the soft magnetic products made of this material have low saturation magnetic induction and poor temperature characteristics, and can only be used in the temperature range below 100°C. When the temperature exceeds this range, its performance will drop sharply or even the magn...
