Neodymium Iron Boron
Ibisabwa bya magneti ya NdFeB byagiye byiyongera cyane ku isoko mpuzamahanga nk'ikoranabuhanga mu itumanaho, Moteri, ibikoresho by'ubuvuzi n'ibindi. Magneti ya Neodymium ikoreshwa cyane mu bice bikurikira: Automation y'ibiro - Mudasobwa bwite, Amakopi, ingufu z'amashanyarazi - Flywheels, Umuyaga w'amashanyarazi Ubumenyi n'Ubushakashatsi - ESR (electron spin resonance), Gukoresha Magnetic, Ubuvuzi bwa Photon - Ubuvuzi bw'amenyo, Inganda zerekana amashusho - Imashini zikoresha inganda, FA (automatike y'uruganda), - Televiziyo, DVD (disiki ya videwo). Ubwikorezi - moteri nto, Sensors, Automobiles, EV (ibinyabiziga byamashanyarazi, imodoka zivanze) Itumanaho - Itumanaho rya mobile, PHS (sisitemu ya terefone igendanwa) Ubuvuzi: MRI, ibikoresho byo kuvura. Gukoresha Buri munsi - Gukoresha ibikoresho bya Magnetique, gukanda magnet kumufuka n imitako, gusaba ibikinisho.

Ferrite / Ceramic
Incamake:
Imashini ihoraho ya ferrite, izwi kandi nka rukuruzi ikomeye, ni ibikoresho bya magnetiki bidafite ubutare. Mu 1930, Kato na Wujing bavumbuye ubwoko bwa spinel (MgA12O4) burigihe, aribwo prototype ya ferrite ikoreshwa cyane muri iki gihe. ya SrO cyangwa Bao na Fe2O3 nkibikoresho fatizo muburyo bwa ceramic (pre firing, guhonyora, pulverizing, gukanda, gucumura no gusya). Ifite ibiranga ubugari bwa hystereze, imbaraga zo guhatira cyane hamwe na remanence. Nubwoko bwibikoresho bikora bishobora kugumya guhora magnetisme iyo imaze gukoreshwa. Ubucucike bwayo ni 4.8g / cm3. Ukurikije uburyo butandukanye bwo gukora, magnite ferrite irashobora kugabanywamo ubwoko bubiri: gucumura no guhuza. Gucumura birashobora kugabanywa gukanda byumye no gukanda, kandi guhuza bishobora kugabanywa gusohora, kwikuramo no guterwa inshinge. Magneti yoroshye, yoroheje kandi ihindagurika ikozwe mu ifu ya ferrite ihujwe na reberi ya sintetike nayo yitwa rubber magnet. Ukurikije niba magnetiki yo hanze ikoreshwa cyangwa idakoreshwa, irashobora kugabanywa muri isotropic ihoraho ya magnet na anisotropique ihoraho.
Gereranya nibindi bikoresho bya magneti
Ibyiza: Igiciro gito, isoko yagutse yibikoresho fatizo, ubushyuhe bwo hejuru (bugera kuri 250 ℃) hamwe no kurwanya ruswa.
Ingaruka: Ugereranije nibicuruzwa bya NdFeB, remanence yayo ni mike cyane. Mubyongeyeho, kubera imiterere isa naho irekuye kandi yoroheje yibikoresho byayo bito, uburyo bwinshi bwo gutunganya bugarukira kuri yo, nko gukubita, gucukura, nibindi, ubwinshi bwibicuruzwa byabwo birashobora gukanda gusa kubibumbano, ibicuruzwa kwihanganira ukuri ni bibi, kandi ikiguzi ni kinini.
Igipfukisho: Bitewe no kurwanya ruswa nziza, ntikeneye gukingirwa.
Samarium cobalt
Magari ya Samarium cobalt ni ubwoko bw'isi idasanzwe. Nubwoko bwibikoresho bya magnetiki bikozwe muri samariyumu, cobalt nibindi byuma bidasanzwe byisi kubutaka, bigashonga mumashanyarazi, kumenagura, gukanda no gucumura. Ifite ingufu za magneti nyinshi hamwe nubushyuhe buke cyane. Ubushyuhe ntarengwa bwo gukora bushobora kugera kuri 350 and, kandi ubushyuhe bubi ntibugira umupaka. Iyo ubushyuhe bwakazi buri hejuru ya 180 ℃, ingufu zayo nini cyane ya magnetiki (BHmax) hamwe no guhatira (co Ubushyuhe bwubushyuhe hamwe nubumara bwimiti biruta ibya NdFeB.
Alnico
Al Ni Co ni umusemburo ugizwe na aluminium, nikel, cobalt, ibyuma nibindi bikoresho byuma. Ifite imbaraga nyinshi, guhatira imbaraga nke, kurwanya ruswa neza, coeffisente yubushyuhe buke, kurwanya ubushyuhe bwinshi, kurwanya ubushuhe, kurwanya ruswa, ntabwo byoroshye okiside kandi ihagaze neza kumurimo. Sintered al Ni Co ikorwa na powder metallurgie. Ikoreshwa cyane mubice byimodoka, ibikoresho, moteri, electroacoustic, itumanaho, magnetoelectric switch, sensor, kwigisha hamwe nikirere.
Rubber Magnet
Imashini zihindagurika zirasa cyane na inshinge zashizweho inshinge ariko zikorerwa mumirongo iringaniye. Izi magneti ziri munsi yimbaraga za magneti kandi ziroroshye cyane bitewe nibikoresho byakoreshwaga murwego hamwe nifu ya magneti. Vinyl ikoreshwa kenshi muri ubu bwoko bwa magneti nka binder.
