ʻO ka wehewehe pōkole:

ʻO Ni76Cr2Cu5 kahi nickel-iron magnetic alloy, me kahi 80% nickel a me 20% hao.Hana ʻia i ka makahiki 1914 e ka physicist Gustav Elmen ma Bell Telephone Laboratories, he mea kaulana ia no kona kiʻekiʻe kiʻekiʻe o ka magnetic permeability, kahi e hoʻohana ai ia ma ke ʻano he kumu magnetic i nā mea uila a me nā lako uila, a me ka pale magnetic e pale ai i nā māla magnetic.Loaʻa i nā huila permalloy pāʻoihana ma kahi o 100,000, i hoʻohālikelike ʻia me kekahi mau tausani no ke kila maʻamau.
Ma waho aʻe o ka permeability kiʻekiʻe, ʻo kāna mau mea magnetic ʻē aʻe he coercivity haʻahaʻa, kokoke i ka magnetostriction zero, a me ka magnetoresistance anisotropic nui.He mea koʻikoʻi ka magnetostriction haʻahaʻa no nā noi ʻoihana, e ʻae iā ia e hoʻohana ʻia i nā kiʻi ʻoniʻoni ʻoniʻoni kahi e hiki ai i nā koʻikoʻi hoʻololi ke hoʻololi i ka nui o nā waiwai magnetic.Hiki ke ʻokoʻa ka pale ʻana o ka uila o Permalloy e like me ka 5% ma muli o ka ikaika a me ke kuhikuhi o kahi kahua magnetic i hoʻopili ʻia.Loaʻa i nā Permalloys ke alo i waena o ke aniani cubic crystal structure me ka lattice mau ma kahi o 0.355 nm ma kahi kokoke i kahi nickel concentration o 80%.ʻO kahi pōʻino o ka permalloy ʻaʻole ia he ductile a hiki ke hana ʻia, no laila, hana ʻia nā noi e koi ana i nā ʻano kikoʻī, e like me nā pale magnetic, i hana ʻia i nā mea hoʻohui kiʻekiʻe e like me ka metala mu.Hoʻohana ʻia ʻo Permalloy i nā laminations transformer a me nā poʻo hoʻopaʻa leo magnetic.
Hoʻohana nui ʻia ʻo Ni76Cr2Cu5 i ka ʻoihana radio-electronic, nā mea hana pololei, ka mana mamao a me ka ʻōnaehana mana.
