    Fa'amatalaga Puupuu:

    O ferrite malo e fa'avae i luga ole barium ferrite ma pauta strontium (fuafua fa'a-kemikolo BaO • 6Fe2O3 ma SrO • 6Fe2O3) gaosia. E aofia ai u'amea oxidized, lea e aofia ai i le vaega mea sima. E aofia ai le approx. 90% iron oxide (Fe2O3) ma le 10% alkaline earth oxide (BaO poʻo SrO) - mea mataʻutia e tele ma taugofie. Latou te vaevaeina i le isotropic ma le anisotropic, o vaega o le vaega mulimuli e fetaui lelei i le tasi
    itu e maua ai uiga maneta sili atu. O maneta Isotropic e fa'apipi'iina a'o fa'apipi'i maneta anisotropic i totonu o se maneta. O lenei mea e maua ai le maneta i se itu e sili ona fiafia i ai ma faatoluina lona malosi malosi.

    Fa'aaliga:
    · Matou te tumau tutusa e pei ona i luga seʻi vagana ua faʻamaonia mai le tagata faʻatau. O le vevela o le Curie ma le fua fa'atatau o le vevela e na'o le fa'asinomaga, ae le o se fa'avae mo le fa'aiuga.· O le maualuga o le vevela galue o le maneta e mafai ona suia ona o le fua faatatau o le umi ma le lautele ma mea tau le siosiomaga.

    Tulaga lelei:

    E pei ona masani ai le oxide ceramics, malo ferrite maneta faʻaalia uiga faʻasaʻo agaʻi atu i le susu, solvents, alkaline solutions,

    vaivai vaivai, masima, lubricants ma kasa filogia. E masani lava, e mafai ona fa'aoga maneta malo ferrite e aunoa ma se puipuiga fa'aopoopo.
    Vaega:
    Ona o lo latou maaa tele (6-7 Mohs), o maneta Ferrite e vaivai ma maaleale i tu'itu'i pe punou. I le taimi o le gaosiga, e tatau ona faʻaogaina i latou i meafaigaluega taimane. O le vevela o galuega fa'atasi ma maneta ferrite e masani lava i le va o le -40ºC ma le 250ºC.

    Talosaga:

    O foliga eseese e faʻaaogaina i le inisinia utomotive, e pei ole masini ma le faʻatonutonuina o fua. O isi fa'aoga e pei o masini eletise ta'avale (wipers, nofoa nofoa afi), A'oa'o, Fa'afaitoto'a, uila fa'amaneta ma le nofoa massage, ma isi.

     

    I aso nei, o ferrites malo e fai ma sui o le vaega pito sili ona tele o maneta tumau na gaosia. I le fa'atusatusa i maneta AlNiCo, ferrites malo e fa'ailoaina i felefele densities ae maualuga malosi fa'amalosi fanua. O le mea lea e maua ai foliga mafolafola masani o mea. Barium ferrite ma strontium ferrite e eseese e faʻatatau i mea amata.

    O tau fa'atatau uma na fa'amauina i le fa'aaogaina o fa'ata'ita'iga masani e tusa ai ma le IEC 60404-5. O fa'amatalaga o lo'o mulimuli mai e fai ma tau fa'asino ma e ono 'ese'ese.
