Maki daban-daban na Bonded NdfeB Magnet

Takaitaccen Bayani:

Bonded NdFeB, wanda ya ƙunshi Nd2Fe14B, maganadisu ce ta roba.Maganar maganadisu ce da aka yi ta hanyar haɗa foda Magnetic NdFeB mai saurin kashewa da ɗaure ta hanyar “gyara matsi” ko “gyaran allura”.Abubuwan maganadisu na NdFeB da aka danna da neodymium wanda aka ƙera allura da baƙin ƙarfe boron maganadisu sune aka fi amfani dasu a cikinsu.
