Sharaxaad Gaaban:

Ni77Mo4Cu5 waa bir bir ah oo bir ah oo nikkel-bir ah, oo leh qiyaastii 80% nikkel iyo 20% bir ah. Waxaa la alifay 1914 fiisikisist Gustav Elmen oo ka tirsan Bell Telephone Laboratories, waana mid caan ku ah awood-siinta bir-gaaban ee aadka u sarreysa, taasoo ka dhigaysa mid waxtar u leh agab bir-gaaban oo ku jira qalabka korontada iyo elektaroonigga ah, iyo sidoo kale gaashaanka bir-gaaban si loo xakameeyo goobaha bir-gaaban. Bir-gaaban ee ganacsiga ee permalloy badanaa waxay leeyihiin awood-gudbinta qiyaastii 100,000, marka la barbar dhigo dhowr kun oo bir ah oo caadi ah.
Marka laga soo tago awood-siinta sare, sifooyinka kale ee birlabta waa qasab yar, meel u dhow eber magnetostriction, iyo magnetoresistance muhiim ah oo anisotropic ah. Magneticostriction-ka hooseeya ayaa muhiim u ah codsiyada warshadaha, taasoo u oggolaanaysa in loo isticmaalo filimada khafiifka ah halkaas oo cadaadiska doorsoomayaashu ay haddii kale sababi karaan kala duwanaansho weyn oo ku yimaada sifooyinka birlabta. Iska caabbinta korontada ee Permalloy way kala duwanaan kartaa ilaa 5% iyadoo ku xiran xoogga iyo jihada goobta birlabta ee la dabaqay. Permalloys-ku waxay caadi ahaan leeyihiin qaab-dhismeedka kiristaalka cubic ee wejiga oo leh joogto shaati ah oo qiyaastii ah 0.355 nm oo ku dhow fiirsashada nikkel ee 80%. Khasaaraha permalloy waa inaysan aad u ductile ahayn ama shaqayn karin, sidaa darteed codsiyada u baahan qaabab faahfaahsan, sida gaashaanka birlabta, waxaa laga sameeyay birlabyo kale oo permeability sare leh sida birta mu. Permalloy waxaa loo isticmaalaa lakabyada transformer-ka iyo madaxyada duubista birlabta.
Ni77Mo4Cu5 si weyn ayaa loogu isticmaalaa warshadaha raadiyaha-elektiroonigga, qalabka saxda ah, kantaroolka fog iyo nidaamka xakamaynta otomaatiga ah.
