Abstract
The invention discloses hard magnetic alloy. The hard magnetic alloy is composed, by mass, 50-70 parts of iron, 30-35 parts of nickel, 25-30 parts of chrome, 5-8 parts of strontium, 1-3 parts of cobalt and 0.5-1 part of barium. The hard magnetic alloy is an alloy material formed by taking the iron as the principal thing and enabling other chemical elements to have a synergistic effect, the magnetic conductivity reaches the standard of soft magnetic materials, and the hard magnetic alloy has the advantages of large coercive force, large residual magnetism and a wide and short magnetic hysteresis loop of hard magnetic materials. Compared with the existing hard magnetic materials, the hard magnetic alloy has the advantages that cost is reduced greatly and service life is prolonged.
Description
Technical field
The present invention relates to magnetically hard alloy, belong to Material Field.
Background technology
Current conventional important permanent magnetic material mainly contains:
(1) rare earth permanent-magnetic material: this is the large class permanent magnetic material that current maximum magnetic energy product is the highest is rare earth element and the iron family element interphase (claiming again intermetallic compound) that is main component.The NdFeB rear-earth alloy permanent magnetic material of China's research and production;
(2) Permanent magnet metallics: this be a large class development and application all early take the alloy-type permanent magnetic material that iron and iron family element (as nickel, cobalt etc.) be important constituent element, mainly containing aluminium nickel cobalt (AlNiCo) is to be two large class permanent-magnet alloys with siderochrome cobalt (FeCrCo).Al-Ni-Co series alloy permanent magnetism performance and cost belong to medium, and early, wider range that performance changes with chemical composition and manufacturing process, therefore range of application is also wider in development.Siderochrome cobalt is that the feature of permanent-magnet alloy is that permanent magnetism performance is medium, but its mechanical property can be carried out various machining and cold or hot plastic deformation, can make tubulose, sheet or wire permanent magnetic material and the multiple special applications of confession;
(3) ferrite permanent-magnet materials: this is to take composite oxides ferromagnetic material (narrow sense) that Fe2O3 is major components and magnetic order material as antiferromagnet (broad sense).Be characterized in that resistivity is high, be particularly conducive in high frequency and microwave applications.As barium ferrite (BaFe12O19) and strontium ferrite (SrFe12O19) etc. has a lot of application.
Except above-mentioned 3 class permanent magnetic materials, also have some manufactures, magnetic and application respectively to have the permanent magnetic material of feature.Such as micropowder permanent-magnetic material, nano permanent magnetic material, glue, mould permanent magnetic material (can be applicable to the sealing of door of refrigerator), workable permanent magnetic material etc.
Current Hard Magnetic material material, cost all very high, conductance not as soft magnetic material, and the life-span fall short of, directly affect the development in the fields such as communication, electricity.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defect, and the magnetically hard alloy that a kind of cost is low, conductance is high and the life-span is long is provided.
Object of the present invention is carried out specific implementation by the following technical programs:
, the mass percent of each element is, iron 50-70 part, nickel 30-35 part, chromium 25-30 part, strontium 5-8 part, cobalt 1-3 part, barium 0.5-1 part.
As preferred version, above-mentioned magnetically hard alloy, the mass percent of each element is, 70 parts of iron, 33 parts, nickel, 26 parts of chromium, 5 parts, strontium, 2.5 parts of cobalts, 0.9 part of barium.
Beneficial effect of the present invention:
Magnetically hard alloy provided by the present invention, take ferro element as main, by other element synergy, and the alloy material of formation, magnetic permeability has reached the standard of soft magnetic material, and has the advantages that the coercive force of hard magnetic material is large, remanent magnetism is large, and magnetic hysteresis loop is wide and short.More existing hard magnetic material has dwindled cost greatly, and be improved useful life.
