Gaar ahaan Neodymium Giraanta Magnet ee Matoorka iyo Afhayeenka
Sharaxaada Alaabta
Neodymium waa bir ductile ah oo la dareemi karo. Neodymium si xoog leh ayuu paramagnetic. Codsiga ugu weyn ee neodymium wuxuu ku jiraa magnets joogto ah oo xoog-sare leh oo ku saleysan Nd2Fe14B kuwaas oo loo isticmaalo matoorrada korantada ee waxqabadka sarreeya iyo koronto-dhaliyeyaasha, iyo sidoo kale magnets-ka Spindle-ka ee darawallada adag ee kombiyuutarka iyo marawaxadaha dabaysha. Magnet-ka Neodymium waxaa laga heli karaa qaabab kala duwan, cabbirro iyo darajooyin kala duwan.
Garaac NdFeB Astaamaha Magnet
1. Heerkulka shaqada oo sarreeya
Magnet-ka giraanta N48H neodymium waxay leeyihiin iska caabin heerkul aad u fiican. Taxanaha NH ee magnets-ka ndFeB, heerkulka ugu badan ee hawlgalka wuxuu gaari karaa 120 ℃.

3. Dahaarka / Duubista
Ikhtiyaarada: Ni-Cu-Ni, Zinc (Zn) , Epoxy Black, Rubber, Gold, Silver, iwm.
4. Jihada magnetic
Magnets giraanta waxaa lagu qeexay saddex cabbir: Dhexroorka dibadda (OD), Dhexroorka Gudaha (ID), iyo Dhererka (H).
Noocyada jihooyinka birlabeedka ee giraanta giraantu waa axially magnetized, diametrically magnetized, radially magnetized, iyo axially magnetized.
