Neodymium Magnet, kwaziwa njengeNdFeb Neodymium umazibuthe, yinkqubo ye-crystal ye-tetragonal eyenziwe yi-neodymium, isinyithi kunye ne-boron.Lo mazibuthe unamandla amakhulu kunawoSmCo Permanent Magnets, eyona magnethi inkulu ehlabathini ngelo xesha.Emva kwexesha, uphuhliso oluyimpumelelo lwesinyithi somgubo, iGeneral Motors iphuhlise ngempumelelo indlela yokunyibilikisa ijethi ejikelezayo, inokuvelisa iimagnethi zeNdFeb.Olu hlobo umazibuthe ngoku lukwindawo yesibini kuphela kwimagnethi esisigxina ye-zero holmium, ikwayimagnethi yomhlaba enqabileyo esetyenziswa ngokuqhelekileyo.Iimagnethi ze-NdFeb zisetyenziswa kakhulu kwiimveliso ze-elektroniki ezinje ngee-hard drives, iiselfowuni, ii-earphones kunye nezixhobo ezisebenza ngebhetri.
Imagnethi yeNdFeb, ekwabizwa ngokuba yimagnethi yomhlaba enqabileyo, luhlobo oluthileIzinto zeMagneticyenziwe kwaye ifakwe kwi-praseodymium neodymium njengeyona mathiriyeli ekrwada.
Ukusetyenziswa kwemagnethi ye-NdFeb kwisandisi-lizwi: kuba icandelo layo eliphambili yi-neodymium kunye ne-alloying element yentsimbi (fe-co), ngoko ibizwa ngokuba yi-NdFeb.Luhlobo lwemagnethi esisigxina enentsebenzo egqwesileyo, esetyenziswa ngokubanzi kushishino lwe-elektroniki, ukwenziwa koomatshini kunye nezixhobo.
I-NdFeb ineempawu ze-remanence ephezulu, ukunyanzeliswa okuphezulu kunye namandla ombane aphezulu.Inokugcina i-magnetism ixesha elide kwiqondo lokushisa eliphezulu ngaphandle kwe-oxygen.Ukuzinza kakuhle kwe-thermal;Inozinzo oluhle lweekhemikhali kunye nokumelana nokugqwala okuphezulu.Isici sayo esikhulu kukuba sinokuzaliswa ngomthamo omkhulu wamagnethi (ukuya kuthi ga kwi-100kg), kwaye intsimi ye-demagnetic incinci kakhulu (ayinanto).Ke ngoko, inombono obanzi wesicelo kwintsimi yemagnethi ephezulu.
Okwangoku, iimveliso zasekhaya ikakhulu ziquka: hf50 ~ 70mm specication series, hf80 ~ 120mm specication series kunye smd series ezintathu iintlobo zeemveliso.Ixabiso leemveliso ngokubanzi lingaphezulu kwe-RMB 20,000 ngekhilogram ukuya kwi-RMB 40,000.
Ngenxa yokuba imveliso isetyenziswa kakhulu kwaye idosi inkulu, ukusetyenziswa kufikelela kumakhulu amawaka eetoni minyaka le.Nangona kunjalo, amazwe ambalwa kuphela emhlabeni anokuvelisa le Mathiriyeli intsha esebenzayo enomxholo wetekhnoloji ephezulu kunye nexabiso eliphezulu elongezelelweyo, "Izinto zeMagnetic ezikumgangatho ophezulu“.
