Materiali magnetici sono materiali funzionali fondamentali dell'industria elettronica. Come importanti parti di materiali magnetici, materiali di ferrite dura giocare un heavyrole nell'industria elettronica, industria dell'informazione elettronica, industria automobilistica, industria ecc. del motociclo nel frattempo, essi sono anche ampiamente utilizzati nel trattamento medico, estrazione mineraria e metallurgia, automazione industriale, industria di energia del petrolio e industria civile. magnete di ferrite, magneti in ferrite, magnete legato della ferrite, magnete di ferrite di bario, magnete di ferrite dura, sinterizzato ferrite magnete, magnete in ferrite incollati iniezione
I nostri prodotti principali comprende: ferrite dura arco o segmento, anelli magnetici, Magneti rettangolari, potenza della ferrite ecc. Che presentano i seguenti vantaggi: alta forza coercitiva, ad alta resistenza elettrica, da sempre stabilità e prezzo economico. Nel frattempo, possiamo fabbricare nuovi strumenti secondo la richiesta dei clienti. magnete di ferrite, magneti in ferrite
