Ohmalloy-1J85yog ib tug npib tsib xee-hlau magnetic alloy, muaj li ntawm 80% nickel thiab 20% hlau ntsiab lus. Tsim nyob rau xyoo 1914 los ntawm tus kws kho mob Gustav Elmen ntawm Tswb Xov Tooj Laboratories, nws yog ib qho tseem ceeb rau nws cov hlau nplaum permeability siab heev, uas ua rau nws muaj txiaj ntsig zoo li cov khoom siv hlau nplaum hauv cov khoom siv hluav taws xob thiab hluav taws xob, thiab tseem muaj kev tiv thaiv sib nqus los thaiv cov hlau nplaum. Kev lag luam permalloy alloys feem ntau muaj txheeb ze permeability ntawm ib ncig ntawm 100, 000, piv rau ntau txhiab rau cov hlau zoo tib yam.
Ntxiv rau qhov siab permeability, nws lwm yam khoom sib nqus yog coercivity tsawg, zero magnetostriction, thiab tseem ceeb anisotropic magnetoresistance. Qhov tsis tshua muaj magnetostriction yog qhov tseem ceeb rau cov ntawv thov kev lag luam, tso cai rau nws siv rau hauv cov yeeb yaj kiab nyias uas muaj kev ntxhov siab sib txawv yuav ua rau muaj kev hloov pauv loj hauv cov khoom sib nqus.
Permalloy's hluav taws xob resistivity tuaj yeem sib txawv li 5% nyob ntawm lub zog thiab cov kev taw qhia ntawm kev siv magnetic teb. Permalloys feem ntau muaj lub ntsej muag nruab nrab cubic siv lead ua qauv nrog lub lattice tas li ntawm kwv yees li 0.355 nm nyob ib puag ncig ntawm nickel concentration ntawm 80%. Ib qho tsis zoo ntawm permalloy yog tias nws tsis yog ductile lossis ua haujlwm tau zoo, yog li cov ntawv thov xav tau cov duab zoo nkauj, xws li cov ntaub thaiv npog sib nqus, yog ua los ntawm lwm cov hlau permeability siab xws li mu hlau. Permalloy yog siv nyob rau hauv transformer laminations thiab magnetic kaw taub hau.
Ohmalloy-1J85yog dav siv nyob rau hauv xov tooj cua-electronic kev lag luam, precision instruments, chaw taws teeb tswj thiab tsis siv neeg tswj system.
