(Magnetic alloy mai laushi)

Ni77mo4cu5 nickel-iron Magnetic Alloy, tare da kusan 80% nickel da 20% baƙin ƙarfe.An ƙirƙira shi a cikin 1914 ta masanin kimiyyar lissafi Gustav Elmen a dakunan gwaje-gwaje na wayar tarho na Bell, sananne ne saboda ƙarfin ƙarfin maganadisu sosai, wanda ya sa ya zama mai amfani a matsayin kayan masarufi a cikin kayan lantarki da na lantarki, da kuma garkuwar maganadisu don toshe filayen maganadisu.Kayayyakin permalloy na kasuwanci yawanci suna da alaƙar dangi kusan 100,000, idan aka kwatanta da dubu da yawa don ƙarfe na yau da kullun.
Bugu da kari ga babban permeability, sauran Magnetic kaddarorin su ne low coercivity, kusa da sifili magnetostriction, da kuma gagarumin anisotropic magnetoresistance.Ƙananan magnetostriction yana da mahimmanci ga aikace-aikacen masana'antu, yana ba da damar yin amfani da shi a cikin fina-finai na bakin ciki inda damuwa mai canzawa zai haifar da babban bambanci a cikin abubuwan maganadisu.Resistance wutar lantarki na Permalloy na iya bambanta kamar 5% ya danganta da ƙarfi da alkiblar filin maganadisu.Permalloys yawanci suna da tsarin lu'ulu'u na lu'u-lu'u na fuskar fuska tare da madaidaicin lattice na kusan 0.355 nm a cikin kusancin tarin nickel na 80%.Rashin lahani na permalloy shine cewa ba shi da ductile ko aiki, don haka aikace-aikacen da ke buƙatar cikakkun siffofi, irin su garkuwar maganadisu, an yi su da wasu manyan abubuwan haɓakawa kamar mu karfe.Ana amfani da Permalloy a cikin laminations masu canzawa da shugabannin rikodin maganadisu.
