Dab tsi yog hom ntawm cov khoom sib nqus mos

① Cov hlau ntshiab thiab cov pa roj carbon tsawg

Cov ntsiab lus carbon hauv qab 0.04%, suav nrog electromagnetic ntshiab hlau thiab electrolytic hlau. Nws cov yam ntxwv yog siab saturation magnetization, tus nqi qis, thiab kev ua haujlwm zoo; Tab sis nws tsis tshua muaj kev tiv thaiv thiab siab eddy tam sim no poob nyob rau hauv alternating magnetic teb tsuas yog haum rau static siv, xws li manufacturing electromagnetic hlau cores, ncej khau, relay thiab hais lus sib nqus conductors, sib nqus shielding npog, thiab lwm yam.

② Ferrosilicon alloy

Cov ntsiab lus silicon nyob ntawm 0.5% mus rau 4.8%, feem ntau hu ua silicon steel ntawv, thiab feem ntau yog siv los ua cov phaj nyias. Ntxiv silicon rau cov hlau ntshiab tuaj yeem tshem tawm qhov tshwm sim ntawm cov khoom sib nqus hloov nrog lub sijhawm siv. Raws li cov ntsiab lus ntawm silicon nce, thermal conductivity txo, lub brittleness nce, thiab saturation magnetization zog txo. Txawm li cas los xij, nws cov resistivity thiab magnetic permeability yog siab, thiab nws coercive quab yuam thiab eddy tam sim no poob yog txo. Yog li ntawd, nws tuaj yeem siv rau thaj tsam ntawm AC, tsim cov hlau cores rau motors, transformers, relays, transformers, thiab lwm yam.

③ Hlau aluminium alloy

Muaj 6% mus rau 16% txhuas, nws muaj cov khoom sib nqus zoo, siab permeability thiab resistivity, siab hardness, zoo hnav tsis kam, tab sis brittleness. Nws yog tsuas yog siv rau kev tsim hlau cores thiab sib nqus taub hau rau me me transformers, magnetic amplifiers, relays, thiab ultrasonic transducers.

④ Hlau silicon aluminium alloy

Tau los ntawm kev ntxiv silicon rau binary hlau aluminium alloy. Nws hardness, saturation magnetic induction intensity, sib nqus permeability, thiab resistivity yog tag nrho cov siab. Qhov tsis zoo yog tias cov khoom sib nqus yog qhov nkag siab rau cov khoom hloov pauv, muaj cov brittleness siab, thiab muaj kev ua haujlwm tsis zoo. Feem ntau yog siv rau lub taub hau audio thiab video.

⑤ Nickel hlau alloy

Cov ntsiab lus nickel nyob ntawm 30% mus rau 90%, tseem hu ua permalloy. Los ntawm cov khoom sib nqus sib piv thiab cov txheej txheem tsim nyog, cov khoom sib nqus tuaj yeem tswj tau kom tau txais cov khoom sib nqus mos xws li cov hlau nplaum sib nqus, qhov sib nqus tsis tu ncua, thiab lub sijhawm sib nqus. Nws muaj plasticity siab thiab rhiab heev rau kev ntxhov siab, thiab tuaj yeem siv los ua cov khoom siv rau kev hloov pauv mem tes, inductor cores, thiab cov khoom siv hlau nplaum ua haujlwm.

⑥ Hlau cobalt alloy

Cov ntsiab lus cobalt yog li ntawm 27% mus rau 50%. Nws muaj siab saturation magnetization thiab tsawg resistivity. Haum rau kev tsim ncej khau, lub cev muaj zog rotors thiab stators, me me transformer cores, thiab lwm yam.

⑦ Mos sib nqus ferrite

Nonmetallic ferrous magnetic soft magnetic cov ntaub ntawv. High resistivity (10-2-1010 Ω · m), qis saturation magnetization dua hlau, thiab tus nqi qis, dav siv raws li inductance thiab transformer Cheebtsam (saib ferrite).

⑧ Amorphous mos magnetic alloy

Ib qho kev txiav txim ntev ntev, tsis muaj hlau tsis muaj hlau, tseem hu ua hlau iav lossis amorphous hlau. Nws muaj cov magnetic permeability thiab resistivity, tsis tshua muaj coercivity, insensitivity rau kev ntxhov siab, thiab tsis muaj magnetic crystal anisotropy tshwm sim los ntawm cov qauv siv lead ua. Nws muaj cov yam ntxwv xws li corrosion kuj thiab siab zog. Tsis tas li ntawd, nws cov ntsiab lus Curie yog qis dua li ntawm cov khoom siv hlau nplaum crystalline mos, zoo heev txo cov hluav taws xob poob, thiab ua rau nws yog hom tshiab ntawm cov khoom siv hlau nplaum uas tau tsim thiab siv.

⑨ Ultra microcrystalline mos magnetic alloy

Ib qho khoom siv hlau nplaum tau pom nyob rau xyoo 1980s. Ua los ntawm crystalline thiab amorphous grain ciam theem tsawg dua 50 nanometers, nws muaj cov khoom zoo dua li cov crystalline thiab amorphous alloys. Nws tsis tsuas yog muaj siab sib nqus permeability, qis coercive quab yuam, tsis tshua muaj hlau poob, tab sis kuj siab saturation magnetic induction zog thiab zoo stability. Lub ntsiab kev tshawb fawb tsom mus rau hlau raws li ultra microcrystalline alloys.
