Magnetau NdFeB Sintered



Disgrifiad

Magnetau NdFeB Sintered yw'r magnetau parhaol masnacheiddio mwyaf pwerus sydd ar gael heddiw, gyda'r cynnyrch ynni mwyaf yn amrywio o 26 MGOe i 52 MGOe. Nd-Fe-B yw'r drydedd genhedlaeth o fagnet parhaol a ddatblygwyd yn yr 1980au. Mae ganddo gyfuniad o barhad a gorfodaeth uchel iawn, ac mae'n dod ag ystod eang o raddau, meintiau a siapiau. Gyda'i nodweddion magnetig rhagorol, digonedd o ddeunydd crai a phrisiau cymharol isel, mae Nd-Fe-B yn cynnig mwy o hyblygrwydd wrth ddylunio deunyddiau magnet newydd neu amnewid fel cerameg, Alnico a Sm-Co i sicrhau effeithlonrwydd uchel, cost isel a mwy dyfeisiau cryno.


Manteision Magnet sintered
* Sefydlu Preswyl Br cryf iawn.
* Gallu gwrthsefyll demagnetization rhagorol.
* Pris Da o'i gymharu â'i briodweddau magnetig uchel.
