Alnico maganadiso yana da simintin gyare-gyare da kuma sintering biyu daban-daban matakai hanyoyi.Abubuwan da ke cikin gida sun fi fitar da Alnico.Samfurin ƙarfin maganadisu na Alnico maganadisu na iya zuwa 9MGOe, kuma yana da babban fasali shine juriya mai zafi, zafin aiki na iya kaiwa digiri Celsius 550.Duk da haka, Alnico maganadisu abu ne mai sauqi don demagnetize a cikin wani jujjuyawar filin maganadisu.Idan kun tura sandunan maganadisu na Alnico guda biyu a wuri guda (N biyu ko biyu S's) tare, filin daya daga cikin maganadisun zai koma baya ko kuma ya koma baya.Saboda haka, bai dace da aiki a cikin wani jujjuyawar filin maganadisu (kamar mota).
Alnico yana da tsayin daka kuma ana iya yanke shi da kuma yanke waya, amma a farashi mai girma.Gabaɗaya samar da kayan da aka gama, akwai nau'ikan niƙa iri biyu masu kyau ko ba niƙa ba.
Ferrite maganadisu / Ceramic magnet
Ferrite wani nau'i ne na kayan maganadisu mara ƙarfe, wanda kuma aka sani da yumbu na maganadisu.Muna ɗaukar rediyo na al'ada baya, kuma maganadisu na ƙaho a cikinsa ferrite ne.
Abubuwan magnetic na ferrite ba su da girma, samfurin makamashi na Magnetic na yanzu (ɗayan sigogi don auna aikin maganadisu) na iya yin 4MGOe kaɗan kaɗan.Kayan yana da babban amfani na kasancewa mai arha.A halin yanzu, ana amfani da shi sosai a fagage da yawa
Ferrite yumbu ne.Saboda haka, aikin injin yana kama da na yumbu.Ferrite maganadiso ne mold forming, sintering fita.Idan ana buƙatar sarrafawa, kawai za a iya yin niƙa mai sauƙi.
Saboda wahalar aiki na inji, don haka yawancin nau'in ferrite yana da sauƙi, kuma girman haƙuri yana da girma.Samfuran siffar square suna da kyau, ana iya niƙa su.Madauwari, gabaɗaya tana niƙa jirage biyu kawai.Ana ba da sauran juriyar juzu'i azaman kashi na ƙima.
