Super Strong N52 Neodymium Magnet Circular Ø50 x 20mm

Honsen Sib Nqusmuag cov ntawv tso cai neodymium hlau nplaum.Cov hlau nplaum neodymium (tseem hu ua NdFeB NIB lossis Neo hlau nplaum) feem ntau siv hom hlau nplaum uas tsis tshua muaj hauv ntiaj teb, yog cov hlau nplaum ruaj khov ua los ntawm cov hlau nplaum ntawm neodymium, hlau thiab boron los tsim Nd2Fe14B tetragonal crystalline qauv.Tsim nyob rau xyoo 1982 los ntawm General Motors thiab Sumitomo Cov Hlau Tshwj Xeeb, cov hlau nplaum neodymium yog hom muaj zog tshaj plaws ntawm cov hlau nplaum ruaj khov uas muag muag.Lawv tau hloov lwm hom hlau nplaum nyob rau hauv ntau daim ntawv thov nyob rau hauv cov khoom niaj hnub uas yuav tsum muaj cov hlau nplaum ruaj khov, xws li cov motors hauv cov cuab yeej cordless, hard disk drives thiab cov hlau nplaum sib nqus.Tsis paub meej tias Neodymium yog cov khoom siv zoo tshaj plaws rau koj daim ntawv thov?nyem qhov no rau tus cwj pwm thiab daim ntawv thov sib piv rau tag nrho cov khoom sib nqus peb muab.

Neodymium puag ncig ruaj khov hlau nplaum Description

Lub tetragonal Nd2Fe14B siv lead ua qauv muaj qhov tshwj xeeb siab uniaxial magnetocrystalline anisotropy (HA ~ 7 teslas-magnetic teb lub zog H hauv A / m piv rau lub sijhawm sib nqus hauv A.m2).Qhov no muab qhov sib xyaw ua ke kom muaj kev sib koom siab siab (piv txwv li, tsis kam ua demagnetized).Lub tebchaw kuj tseem muaj cov hlau nplaum siab saturation (Js ~ 1.6 T lossis 16 kG) thiab feem ntau yog 1.3 teslas.Yog li ntawd, raws li lub zog siab tshaj plaws yog proportional rau js2, lub sij hawm sib nqus no muaj peev xwm khaws cia ntau lub zog sib nqus (BHmax ~ 512. kJ/m3 lossis 64 MG·Oe) Cov cuab yeej no muaj ntau dua nyob rau hauv NdFeB alloys dua li cov hlau nplaum samarium cobalt (SmCo), uas yog thawj hom hlau nplaum uas tsis tshua muaj hauv ntiaj teb yuav tsum tau ua lag luam.Hauv kev xyaum, cov khoom sib nqus ntawm cov hlau nplaum neodymium nyob ntawm qhov sib xyaw alloy, microstructure, thiab cov txheej txheem tsim khoom siv.n45 neodymium hlau nplaum disc
