Kev cai Neodymium Nplhaib Magnet rau Tsav thiab Hais Lus
Product Description
Neodymium yog ib qho khoom siv zoo nkauj thiab zoo nkauj silvery-dawb hlau. Neodymium muaj zog paramagnetic. Daim ntawv thov loj ntawm neodymium yog nyob rau hauv high-zog mus tas li hlau nplaum raws li Nd2Fe14B uas yog siv nyob rau hauv high-kev ua tau zoo hluav taws xob motors thiab generators, raws li zoo raws li nyob rau hauv spindle hlau nplaum rau lub computer hard drives thiab cua turbines. Neodymium hlau nplaum muaj nyob rau hauv ntau hom duab, qhov ntau thiab tsawg thiab qib.Ring hlau nplaum zoo li cov discs lossis lub tog raj kheej, tab sis nrog lub qhov nruab nrab.
Nplhaib NdFeB Magnet Yam ntxwv
1. Ua haujlwm kub
N48H neodymium nplhaib hlau nplaum muaj qhov kub thiab txias. Rau NH series NdFeB hlau nplaum, qhov siab tshaj plaws ua haujlwm kub tuaj yeem ncav cuag 120 ℃.

3. Txheej / Plating
Kev xaiv: Ni-Cu-Ni, Zinc (Zn), Dub Epoxy, Roj Hmab, Kub, Nyiaj, thiab lwm yam.
4. Kev taw qhia sib nqus
Lub nplhaib hlau nplaum yog txhais los ntawm peb qhov ntev: Sab Nraud (OD), Sab Hauv (ID), thiab qhov siab (H).
Cov kev taw qhia sib nqus ntawm cov nplhaib hlau nplaum yog axially magnetized, diametrically magnetized, radially magnetized, thiab multi-axially magnetized.
