1j77 Soft Magnetic Alloy Waya Ni77Mo4Cu5

Apejuwe kukuru:

Ni77Mo4Cu5 jẹ alloy oofa nickel-irin, pẹlu bii 80% nickel ati 20% akoonu irin. Ti a ṣe ni ọdun 1914 nipasẹ onimọ-jinlẹ Gustav Elmen ni Awọn ile-iṣẹ Tẹlifoonu Bell, o jẹ ohun akiyesi fun agbara oofa rẹ ti o ga pupọ, eyiti o jẹ ki o wulo bi ohun elo mojuto oofa ninu itanna ati ohun elo itanna, ati tun ni aabo oofa lati dènà awọn aaye oofa. Awọn alloy permalloy ti iṣowo ni igbagbogbo ni agbara ibatan ti o to 100,000, ni akawe si ọpọlọpọ ẹgbẹrun fun irin lasan.
Ni afikun si ailagbara giga, awọn ohun-ini oofa miiran jẹ iṣiṣẹpọ kekere, nitosi odo magnetostriction, ati pataki anisotropic magnetoresistance. Iwọn magnetostriction kekere jẹ pataki fun awọn ohun elo ile-iṣẹ, gbigba laaye lati ṣee lo ni awọn fiimu tinrin nibiti awọn aapọn oniyipada yoo bibẹẹkọ fa iyatọ nla ti iparun ni awọn ohun-ini oofa. Atako eletiriki Permalloy le yatọ bi 5% da lori agbara ati itọsọna aaye oofa ti a lo. Permalloys ni igbagbogbo ni oju ti dojukọ okuta kristali onigun pẹlu ibakan latintice ti isunmọ 0.355 nm ni agbegbe ifọkansi nickel kan ti 80%. Aila-nfani ti permalloy ni pe kii ṣe ductile pupọ tabi ṣiṣẹ, nitorinaa awọn ohun elo ti o nilo awọn apẹrẹ ti o ni ilọsiwaju, gẹgẹbi awọn apata oofa, ni a ṣe ti awọn alloy permeability giga miiran gẹgẹbi mu irin. A lo Permalloy ni awọn laminations transformer ati awọn olori gbigbasilẹ oofa.
Ni77Mo4Cu5 ti a lo pupọ ni ile-iṣẹ redio-itanna, awọn ohun elo titọ, iṣakoso latọna jijin ati eto iṣakoso adaṣe.
