Magnet manufacturer material classification characteristics and USES
Permanent magnetic material: magnet magnetized thick except to still has strong magnetic field, is characterized by high coercive force and magnetic energy product.
Magnet manufacturer material classification characteristics and purposes can be divided into three categories, permanent magnet, metal, aluminum nickel and cobalt, cobalt and rare earth rubidium iron boron, etc.
Ferrite permanent magnet, cases, barium ferrite, strontium ferrite and other permanent magnet, such as plastic, etc.
Soft magnetic materials: easy magnetization and demagnetization of materials.
Manganese zinc ferrite soft magnetic materials, its operating frequency in k - 1
Between 10 m.
Nickel zinc ferrite soft magnetic materials, the working frequency is in commonly 1 -
Compared with ferrite, metal soft magnetic material: with high saturation magnetic induction intensity and low coercive force, such as pure iron, iron alloy, iron, cobalt alloy iron nickel alloy, etc. , often used in transformers, etc.
Ferrite magnetic materials, and magnet manufacturers generally refers to the iron oxide and other metal oxides in oxide.
Most ferrous magnetic.
Features: high resistivity than metal, approximately 1 -
European/cm, so vortex loss and skin effect is small, suitable magnetic steel used in high frequency.
Saturation magnetization intensity is low, not suitable for high magnetic density.
Curie temperature is lower.
Ferromagnetic materials: refers to has a ferromagnetic material.
Iron nickel, cobalt and their alloys, for example, some rare earth elements of the alloy.
Below the Curie temperature, when the external magnetic material has larger magnetization.
Ferrous magnetic material: refers to a ferrous magnetic materials, such as all kinds of ferrite, at a temperature below that at which endure the magnets, magnet manufacturer, when the external magnetic material has larger magnetization.
