Leman Neyodim ki te fusion ansanm yo konstwi nan materyèl Nd-Fe-B fò ak yon lyan epoksidik. Apeprè 97 pousan vol nan melanj lan se materyèl leman, ak 3 pousan vol se epoksidik. Nd-Fe-B poud ak yon lyan epoksidik yo konbine pandan pwosesis fabrikasyon an, ki gen ladan tou konpresyon melanj lan nan yon laprès ak geri pati a nan yon fou. Depi materyèl la kreye lè l sèvi avèk lyezon konpresyon, dimansyon yon kouri nòmalman pral varye pa plis pase .002 pous.
Leman neyodim-fè-bor (NdFeB) yo itilize nan yon varyete aplikasyon. Kouch epoksidik pi souvan itilize pou leman NdFeB kole. Electroless nikèl plating tou itilize pou anpeche korozyon. Nenpòt direksyon oswa yon kantite poto ka itilize pou magnetize materyèl NdFeB ki mare izotwopi.
Kòm leman sa a se izotwòp, li ka magnetize nan nenpòt direksyon, menm lè l sèvi avèk plizyè konfigirasyon polè. Akòz lyan epoksidik materyèl la, li ka usinage sou yon moulen oswa tour. Sepandan, twou pa ka tape paske materyèl la pa pral kenbe yon fil. Yo nan lòd yo siyifikativman minimize gwosè a nan desen ki itilize materyèl leman seramik, leman NdFeB lye yo souvan itilize. Materyèl la apeprè twa fwa pi fò pase materyèl leman seramik, sa ki pèmèt rediksyon gwosè enpòtan. Materyèl la kapab tou mayetize milti-polè paske li se izotwòp, tankou pa kreye yon modèl NSNS sou sikonferans deyò yon bag.
