Abstract
The invention relates to a weak-magnetism alloy material. The weak-magnetism alloy material is of a FeCOMSiBTi base material, and comprises the following compositions in atomic percentage (at%): 20-25% of cobalt, 3-5% of M, 8-12% of silicon, 10-15% of boron, 1.5-2.5% of titanium and the rest of ferrum and a small amount of inevitable impurities, wherein M is one or combination of copper, niobium, molybdenum, vanadium and zirconium.
Description
Technical field
The invention belongs to field of functional materials, refer to especially a kind of weak magnetic alloy material.
Background technology
In the prior art, magnetic material particularly magnetic material is used as producing the product that high frequency transformer, magnetic head etc. need to utilize magnetic material properties.Magnetic material refers to compare the magnetic material with demagnetization performance with permanent magnetic material.The now production of main magnetic material prepares with Ferrite Material substantially, and the key property of this class Ferrite Material is the advantages such as resistivity is high, and the high-frequency vortex loss is little.But the saturation induction density of the magnetic product of this material preparation is on the low side, temperature characterisitic is poor, only can be used in the scope that temperature is lower than 100 ℃, when temperature surpasses this scope, its performance sharply descends even magnetic disappears, so this class material is not suitable for the application under the hot conditions.
China's patent 20041002990 provides a kind of FeCOMSiB of employing alloy material and has improved the consumption of Co element.Although this technical scheme can have higher temperature characterisitic, contain Co high magnetic alloy storage magnetic property and demagnetization speed not high, CO belongs to narrow resources with respect to China simultaneously, and the import dependency degree surpasses more than 90%, therefore is necessary prior art is improved.
Summary of the invention
The objective of the invention is by improvements over the prior art, also can improve the demagnetization performance of this class magnetic material at the temperature characterisitic that guarantees magnetic material and storage magnetic property.
The present invention is achieved by the following technical solutions:
A kind of weak magnetic alloy material, described magnetic alloy material is the FeCOMSiBTi base material, each composition forms and comprising by atomic percentage conc (at%): the cobalt of 20-25, the M of 3-5, the silicon of 8-12, the boron of 10-15,1.5-2.5 titanium, all the other are iron and a small amount of inevitably impurity; Described M is one or more combination in copper and niobium, molybdenum, vanadium, the zirconium.
The atomic percentage conc of described copper (at%) is 0.8-1.2; The atomic percentage conc of one or more combination (at%) is 3.5-4.5 in described niobium, molybdenum, vanadium, the zirconium.
Further improve, described M is the combination of copper and vanadium.
The invention has the beneficial effects as follows:
Compare with prior art, this magnetic material alloy has preferably hot properties and storage magnetic property, is for the preferred magnetic material of making magnetic head.
Embodiment
So that the present invention is described in detail, select in this application the performance of organizing embodiment more and drawing each component by the detection to each embodiment below in conjunction with specific embodiment.6 groups of embodiment have been selected altogether in this application.

The atomic percentage conc of described copper (at%) is 0.8-1.2; The atomic percentage conc of one or more combination (at%) is 3.5-4.5 in described niobium, molybdenum, vanadium, the zirconium.
Described M is the combination of copper and vanadium.
The preparation of embodiment is to carry out melting in vaccum sensitive stove, at first will be evacuated to 10 in the stove
-3More than the Pa; then be filled with 1 atmospheric argon gas, melting is to adopt argon shield and through being cast into the alloy base substrate after the electromagnetic agitation fully, again base substrate is being processed into semi-finished product according to need; again through 500-520 ℃ and 30 minutes annealing of insulation, then to product test.
The testing experiment of product
The measurement of magnetic permeability is to be 10 in vacuum degree
-3Carry out in the Pa vacuum furnace, metering system employing heating rate is that 3.5 ℃/minute linear temperature increase is measured.Through measuring, the technical program has good temperature characterisitic.
The concrete composition of embodiment 1-6 sees Table 1
The atomic percent at% of composition (table 1) unit of various embodiments of the present invention
Can show by above measurement result, technical scheme of the present invention is similar with the performance of the magnetic material that rolls up cobalt content in the prior art, but cost reduces in a large number.
