Sharaxaad Gaaban:

Ni77Mo4Cu5 waa bir bir ah oo bir ah, oo ka kooban 80% nikkel iyo 20% maaddo bir ah. Waxa alifay 1914kii physicist Gustav Elmen oo ka tirsan Shaybaadhka Telefoonka Bell, waxa ay caan ku tahay xajmigeeda magnetic aadka u sarreeya, taas oo ka dhigaysa mid faa'iido u leh sida walxaha xudunta u ah magnetka ee qalabka korantada iyo elektiroonigga ah, iyo sidoo kale gaashaanka magnetka si loo xannibo meelaha magnetic. Alaabooyinka loo yaqaan 'permalloy-ka ganacsiga' waxay caadi ahaan leeyihiin awood-dhaaf ah ilaa 100,000, marka la barbar dhigo dhowr kun oo birta caadiga ah.
Marka laga soo tago daah-furnaanta sare, sifooyinkeeda kale ee birlabeedka ayaa ah qasbid hoose, oo u dhow magnetostriction eber, iyo magnetoresistance anisotropic oo muhiim ah. Magnetostriction-ka hooseeya ayaa muhiim u ah codsiyada warshadaha, taas oo u oggolaanaysa in loo isticmaalo filimada khafiifka ah halkaas oo cadaadiska isbeddelka ahi uu haddii kale keeni karo kala duwanaansho weyn oo ah guryaha magnetic. Iska caabbinta korantada ee Permalloy way kala duwanaan kartaa ilaa 5% iyadoo ku xidhan xoogga iyo jihada goob birlabeedka codsatay. Permalloys caadi ahaan waxay leeyihiin qaab dhismeed cubic crystal ah oo udub dhexaad u ah wejiga oo leh shabag joogto ah oo ku dhow 0.355 nm agagaarka nikkel 80%. Khasaarada permalloy waa iyada oo aan ahayn mid aad u jilicsan ama la shaqeyn karo, sidaas darteed codsiyada u baahan qaabab faahfaahsan, sida gaashaanka magnetic, waxay ka samaysan yihiin alaabo kale oo sarreeya sida mu birta. Permalloy waxaa loo isticmaalaa in lagu dhejiyo qalabka wax lagu beddelo iyo madax duubista magnetic.
Ni77Mo4Cu5 si weyn loogu isticmaalo warshadaha raadiyaha-electronic, qalabka saxda ah, kontoroolka fogaanta iyo nidaamka xakamaynta tooska ah.
