Kufotokozera Kwachidule:

Ni77Mo4Cu5 ndi nickel-iron magnetic alloy, pafupifupi 80% nickel ndi 20% chitsulo. Adapangidwa mu 1914 ndi wasayansi Gustav Elmen ku Bell Telephone Laboratories, ndizodziwikiratu chifukwa champhamvu kwambiri maginito, zomwe zimapangitsa kuti zikhale zothandiza ngati maginito pazida zamagetsi ndi zamagetsi, komanso pakuteteza maginito kuti atseke maginito. Zosakaniza zamalonda za permalloy zimakhala ndi permeability pafupifupi 100,000, poyerekeza ndi zikwi zingapo zachitsulo wamba.
Kuphatikiza pa kupenya kwakukulu, maginito ake ena ndi otsika kwambiri, pafupi ndi zero magnetostriction, ndi anisotropic magnetoresistance. Kutsika kwa magnetostriction ndikofunika kwambiri pamafakitale, kulola kugwiritsidwa ntchito m'mafilimu owonda pomwe kupsinjika kosinthika kungayambitse kusinthika kwakukulu kwa maginito. Mphamvu yamagetsi ya Permalloy imatha kusiyanasiyana mpaka 5% kutengera mphamvu ndi komwe kumayendera maginito. Permalloys nthawi zambiri amakhala ndi nkhope yokhazikika ya ma kiyubiki kristalo yokhala ndi lattice yokhazikika pafupifupi 0.355 nm pafupi ndi faifi tambala 80%. Choyipa cha permalloy ndikuti sichotsika kwambiri kapena chogwira ntchito, chifukwa chake ntchito zomwe zimafunikira mawonekedwe apamwamba, monga zishango zamaginito, zimapangidwa ndi ma alloys ena apamwamba kwambiri monga mu zitsulo. Permalloy imagwiritsidwa ntchito pazitsulo za transformer ndi mitu yojambulira maginito.
Ni77Mo4Cu5 imagwiritsidwa ntchito kwambiri pamakampani a wailesi-magetsi, zida zolondola, zowongolera zakutali komanso makina owongolera.
