Cov ntaub ntawv mos sib nqus xa mus rau thaum lub magnetization tshwm sim ntawm Hc tsis ntau dua 1000A / m, cov ntaub ntawv no hu ua mos hlau nplaum. Cov ntaub ntawv mos sib nqus tuaj yeem ua tiav qhov siab tshaj plaws magnetization nrog tsawg kawg sab nraud magnetic teb. Cov khoom sib nqus mos Cov khoom siv hlau nplaum uas tsis muaj coercivity thiab siab permeability.
Cov ntaub ntawv sib nqus mos yog yooj yim rau magnetize thiab yooj yim rau demagnetize, thiab yog dav siv hauv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob. Cov khoom siv hlau nplaum uas siv ntau tshaj plaws yog hlau-silicon alloy (silicon steel ntawv) thiab ntau yam mos sib nqus ferrites.
① Ntshiab hlau thiab me me hlau
Cov ntsiab lus carbon tsawg dua 0.04%, suav nrog electromagnetic ntshiab hlau, electrolytic hlau thiab carbonyl hlau. Nws yog tus cwj pwm los ntawm qhov siab saturation magnetization, tus nqi qis thiab kev ua haujlwm zoo; Txawm li cas los xij, nws qhov kev tiv thaiv qis thiab qhov poob tam sim no nyob rau hauv alternating magnetic teb tsuas yog tsim nyog rau kev siv zoo li qub, xws li kev tsim cov tshuab electromagnetic cores, ncej boots, relays thiab loudspeaker magnetic conductors, magnetic shielding npog, thiab lwm yam.
② Hlau-silicon alloy
Silicon cov ntsiab lus 0.5% ~ 4.8%, feem ntau yog ua los ntawm cov ntawv nyias siv, feem ntau hu ua silicon steel ntawv. Tom qab qhov sib ntxiv ntawm silicon rau cov hlau ntshiab, qhov tshwm sim uas cov khoom sib nqus ntawm cov khoom sib nqus hloov nrog lub sijhawm siv tuaj yeem raug tshem tawm. Nrog rau qhov nce ntawm silicon cov ntsiab lus, thermal conductivity txo, lub brittleness nce, thiab saturation magnetization txo, tab sis nws resistivity thiab permeability yog siab, thiab coercivity thiab eddy tam sim no poob yog txo, thiaj li hais tias nws yuav siv tau rau lub teb ntawm AC los tsim cov tub ntxhais hlau ntawm cov motors, transformers, relays, transformers, thiab lwm yam.
③ Hlau aluminium alloy
Muaj 6% mus rau 16% txhuas, nrog cov khoom sib nqus zoo, siab permeability thiab resistivity, siab hardness, zoo hnav tsis kam, tab sis nkig, feem ntau yog siv rau hauv kev tsim cov me me transformers, sib nqus amplifiers, relays thiab lwm yam hlau cores thiab hau, ultrasonic transducers.
④ hlau silicon aluminium alloy
Nws yog tau los ntawm kev ntxiv silicon rau binary ferroaluminium alloy. Nws hardness, saturation magnetic induction zog, permeability thiab resistivity yog siab. Qhov tsis zoo yog tias cov cuab yeej sib nqus yog rhiab rau qhov hloov pauv ntawm qhov sib xyaw, qhov brittleness loj, thiab kev ua haujlwm tsis zoo. Feem ntau yog siv rau lub taub hau audio thiab video.
⑤ Nickel-hlau alloy
Nickel cov ntsiab lus ntawm 30% ~ 90%, tseem hu ua Permalloy, los ntawm cov khoom siv alloying piv thiab cov txheej txheem tsim nyog, tuaj yeem tswj cov khoom sib nqus, tau txais permeability siab, permeability tsis tu ncua, lub sij hawm sib nqus thiab lwm yam khoom siv hlau nplaum. Nws muaj cov yas siab thiab muaj kev ntxhov siab ntau dua, thiab tuaj yeem siv los ua cov khoom siv hluav taws xob, cov tub ntxhais inductance thiab cov khoom siv hlau nplaum.
⑥ Fe-Cobalt alloy
Cov ntsiab lus cobalt 27% ~ 50%. Nws muaj siab saturation magnetization thiab tsawg resistivity. Haum rau kev tsim cov ncej khau, lub cev muaj zog rotor thiab stator, me me transformer core, thiab lwm yam.
⑦ Mos sib nqus ferrite
Non-metallic ferromagnetic mos magnetic khoom. High resistivity (10-2~1010Ω·m), qis saturation magnetization dua hlau, tus nqi qis, dav siv los ua inductors thiab transformer Cheebtsam (saib ferrite).
⑧ amorphous mos magnetic alloy
Ib qho tsis-ntev-ntev xaj, tsis-crystalline alloy, tseem hu ua hlau iav, lossis amorphous hlau. Nws muaj permeability siab thiab resistivity, tsis tshua muaj coercivity, tsis muaj rhiab heev rau kev ntxhov siab, tsis muaj magnetic crystal anisotropy tshwm sim los ntawm cov qauv siv lead ua, corrosion kuj thiab siab zog. Tsis tas li ntawd, nws cov ntsiab lus Curie yog qis dua cov khoom siv hlau nplaum crystalline mos, lub zog poob qis heev, yog cov khoom siv hlau nplaum tshiab hauv kev tsim kho thiab siv.
⑨ ultramicrocrystalline mos magnetic alloy
Ib qho khoom siv hlau nplaum tau pom nyob rau xyoo 1980s. Nws yog tsim los ntawm crystalline theem thiab amorphous grain ciam theem tsawg dua 50 nm. Nws muaj cov khoom zoo dua qub dua li crystalline thiab amorphous alloys. Nws tsis tsuas yog muaj siab permeability, tsis tshua muaj coercivity, tsis tshua muaj hlau poob, tab sis kuj muaj siab saturation magnetic induction zog thiab zoo stability. Tam sim no cov kev tshawb fawb tseem ceeb yog hlau puag ultramicrystalline alloy.
