Ferrite is a ferromagnetic metal oxide.
In terms of electrical characteristics, the resistivity of ferrite magnetic material is much bigger than metals and alloys, but also high dielectric properties.
Ferrite magnetic can also performance in high frequency with high magnetic permeability.
Therefore, ferrite has become a high-frequency weak current widely used in the field of magnetic material, not of metal.
Because of the ferrite magnetic energy stored in the unit volume is low, and a low saturated magnetization intensity (
Usually only pure iron 1/3 ~ 1/5)
, thus limits its higher requirements in the low-frequency magnetic energy density in the field of high voltage and high power applications.
Ferrite is composed of iron oxide and other ingredients of sintering.
Generally can be divided into permanent magnetic ferrite magnetic ferrite, soft magnetic ferrite and three.
Magnet manufacturer is used in the process of hot rolled steel from the steel billet rolling off the surface of iron scale (
Plate shaped iron oxide)
After removing impurity, crush, add a small amount of other substances into die extrusion forming, and then in the reducing furnace (
Sintering process, part of the oxide reduction in ferrite, cooling, to the exciter in the magnetization.
Than they are high-grade some magnetic steel, magnetic steel is a real steel, component in addition to iron, basically have higher concentration of nickel.
It usually with intermediate frequency electric furnace smelting (
Only a few kilograms) per furnace
, casting molding, because of its certain plane have precision requirements, usually with a grinding machine for grinding processing.
The magnetization, then become a product.
All kinds of electric meter in measurement of electricity use this magnetic steel.
More advanced alien magnet material is ndfeb magnets.
They are containing rare earth element neodymium iron and boron in the material.
Production is based on the method of cemented carbide production: through pulverizing - mixing - mold - sintering - finishing - the magnetization.
These magnets magnetic field intensity is highest, the best performance, the most expensive.
Is will only be used in national defense and precision equipment.
Electronic list of stepper motor rotor is.
Oh, maglev train must be with this kind of magnetic materials.
