Classification Ferrite Magnets

Ferrite magnets are sintered permanent magnets , barium and strontium iron body composition, in addition to this there is a strong anti- magnetic demagnetization performance , as well as low-cost advantage. Rigid and brittle ferrite magnets , require special machining processes. Magnet due to its heterosexual orientation along the direction of manufacture shall be taken along the direction of magnetization and their homosexual orientation because there is no magnet can be magnetized in any direction , even though surface pressure is often minimal side will find slightly stronger magnetic induction . Energy product in the range 1.1MGOe to 4.0MGOe. Due to the low cost ferrite magnets have broad applications , from motors, loudspeakers to toys , crafts , and thus is the most widely used permanent magnet materials .

It is the main raw materials include ferrite magnets BaFe12O19 and SrFe12O19. Manufacturing method made by ceramic technology , texture hard, brittle materials is due to ferrite magnets have good temperature resistance , low prices , moderate performance, has become the most widely used permanent magnets.

Classification ferrite magnets rarely , only nickel-zinc ferrite magnet and Mn-Zn ferrite magnets. Although only one word, but their frequency of use but has a significant and severe differences.

Permeability ferrite magnet exceptionally high , as opposed to a low-frequency impedance of which is very significant , the high frequency impedance of the correspondingly small . Ferrite magnet can be different according to the needs of industry to a different selection of appropriate technology , to produce the magnet . Ferrite bead at different frequencies will have different resistive . Its impedance versus frequency bump of proportional , should the frequency increases, it will rise sharply out of the ferrite magnet resistive realized .

These reflect the ferrite magnets is also its own characteristics that promote the use of that individual features is its usefulness . However, due to the use of the frequency of contact , ferrite magnet has two categories, then the use of the scale of these two categories is not the same, so the use of the process must be tough to distinguish , so the difference between the right caliber of iron proper use of ferrite magnets .
