Iimagnethi zeSintered NdFeB zezona zineemagnethi ezinamandla ezorhwebo ezinamandla ezikhoyo namhlanje, kunye nemveliso yamandla ephezulu ukusuka kwi-26 MGOe ukuya kwi-52 MGOe. U-Nd-Fe-B sisizukulwana sesithathu semagnethi esisigxina esiphuhliswe kwii-1980s. Inokudityaniswa kobungakanani obuphezulu kunye nokunyanzelwa, kwaye iza noluhlu olubanzi lwamabanga, ubungakanani kunye neemilo. Ngeempawu zayo ezibalaseleyo zemagnethi, ubuninzi bempahla eluhlaza kunye namaxabiso asezantsi kakhulu, u-Nd-Fe-B ubonelela ngokuguquguquka ngakumbi kuyilo olutsha okanye ukubuyisela izinto zemagnethi zemveli ezinje ngeceramic, iAlnico kunye neSm-Co ukufezekisa ukusebenza okuphezulu, iindleko eziphantsi kunye nokunye izixhobo ezihambelanayo.

Izinto eziluncedo Magnet sintered
* Ukomelela okunamandla kwindawo yokuhlala yaseBr.
* Ukuqaqamba kokuchasana nedemagnetization.
* Ixabiso elifanelekileyo malunga neempawu zalo eziphezulu zemagneti.
