Inkcazelo emfutshane:

I-Ni77Mo4Cu5 i-nickel-iron magnetic alloy, malunga ne-80% ye-nickel kunye ne-20% ye-iron content.Yaqanjwa ngo-1914 yingcali yefizikhi uGustav Elmen eBell Telephone Laboratories, iphawuleka ngokungena kwayo kumagnethi aphezulu, nto leyo eyenza ukuba ibe luncedo njengesixhobo esingundoqo sombane kwizixhobo zombane neze-elektroniki, kunye nakwimagnethi yokukhusela ukuvala imagnethi.Iialloyi zorhwebo ze-permalloy zikholisa ukuba ne-permeability emalunga ne-100,000, xa kuthelekiswa namawaka aliqela entsimbi eqhelekileyo.
Ukongeza ekungeneni okuphezulu, ezinye iipropathi zayo zemagneti kukunyanzeliswa okuphantsi, kufutshane ne-zero magnetostriction, kunye ne-anisotropic magnetoresistance ebalulekileyo.I-magnetostriction ephantsi ibalulekile kwizicelo zemizi-mveliso, ukuyivumela ukuba isetyenziswe kwiifilimu ezibhityileyo apho uxinzelelo oluguquguqukayo lunokuthi ngenye indlela lubangele umahluko omkhulu owonakalisayo kwiipropathi zemagneti.Ukuxhathisa kombane kwePermalloy kunokwahluka ukuya kuthi ga kwi-5% ngokuxhomekeke kumandla kunye necala lendawo yemagnethi esetyenziswayo.Iipermalloys ngokuqhelekileyo zinobuso obugxile kwi-cubic crystal structure ene-lattice engaguqukiyo malunga ne-0.355 nm kwindawo yoxinzelelo lwe-nickel ye-80%.Into engalunganga ye-permalloy kukuba ayicoli kakhulu okanye ayisebenzeki, ngoko ke izicelo ezifuna iimilo ezicokisekileyo, ezifana nezikhuselo zemagneti, zenziwe ngezinye iialloyi eziphezulu zokungena ezinje ngesinyithi.I-Permalloy isetyenziswe kwi-transformer laminations kunye neentloko zokurekhoda kwamagnetic.
I-Ni77Mo4Cu5 isetyenziswa ngokubanzi kwishishini le-radio-electronic, izixhobo ezichanekileyo, ulawulo olukude kunye nenkqubo yokulawula ngokuzenzekelayo.
