1.Qhov txawv txav
Ndfeb muaj zog hlau nplaum vim qhov yooj yim oxidation ntawm hlau neodymium, xav tau nto plating. Thiab aluminium nickel cobalt zoo dua corrosion kuj, feem ntau tsis kho deg.
2. Khoom siv
Qhov tawg ntawm ob yam khoom sib txawv. Neodymium Fe-B yog cov siv lead ua me me zoo heev, thiab ntu ntawm txhuas nickel cobalt yog rougher, crystal particles loj dua.
3.Cov Ntws Ntes
Yog tias muaj cov xwm txheej, koj tuaj yeem txiav txim siab ob hom khoom siv hlau nplaum los ntawm demagnetization nkhaus, ndFeb remanence siab dua.
4.Tub kub tsis kam
Ndfeb feem ntau tiv taus 80 degree. Al-ni cobalt hlau nplaum ntawm 300-- 500 degree (Al-Ni cobalt hlau nplaum nyob rau hauv ntau tshaj 600 degree demagnetizing kub, yog li peb feem ntau hais tias Al-Ni cobalt sib nqus hlau ua haujlwm kub yog tsawg dua lossis sib npaug li 550 degree ).
5.Lub zog ntawm Magnetic Force
Aluminium npib tsib xee cobalt yog cov hlau nplaum kub tiv taus, tab sis cov hlau nplaum tsis muaj zog, qhov siab dua qhov kub tsis kam ntawm cov hlau nplaum, qhov tsis muaj zog ntawm cov hlau nplaum. Lub zog sib nqus yog qhov sib npaug ntawm qhov ntsuas kub, zoo li ferrite, ferrite kuj tseem tiv taus kub ntau dua NdFeb.
6.Magnetic Khoom ntom ntom
NdFeB 7.5-7.6g/cm3, AlNiCo 7.3-7.4. Xya, tus nqi ntawm AlNiCo vim yog lub tswv yim kev pab cuam ntawm cobalt thiab npib tsib xee, yog li tus nqi yog kim, tsawg tus neeg, ntau cov neeg muas zaub xaiv NdFeB hloov, AlNiCo daim ntawv thov teb muaj xws li aerospace, tub rog teb, tsheb kev lag luam thiab kev ruaj ntseg system. Saum toj no yog qhov sib txawv ntawm NdFeB thiab AlNiCo, qhov pom ntawm qhov sib txawv yog qhov ncaj, yooj yim thiab ceev.
