Khoom Taw Qhia

"Permalloy" yog ntau yam hu ua Mo-permalloy, Mumetal, Ultraperm thiab Super-malloy, tab sis peb tsuas yog hu nws "Permalloy" hereinafter.

Permalloy feem ntau tshwm sim los ntawm high-magnetic permeability, qis coerive thiab hysteresis. Nws kuj tseem siv los ua ib feem rau ob qho tib si saturating thiab tsis-saturating

Sunbow txaus siab rau koj cov kev xav tau tsis tsuas yog EI lamination cores, sib nqus-shielding rooj plaub, tab sis kuj strip-qhov txhab.

Tag nrho cov no tau ua tiav los txhim kho cov yam ntxwv zoo sib nqus ntawm permalloy

Feem ntau siv rau xoom theem tam sim no transformers thiab GFCI coils.
High pib permeability thiab saturation magnetic induction.
Zoo kuj tiv thaiv siab tam sim no impulse.

Mos magnetic alloy-1J85(Lub Npe: Ni80Mo5, E11c, permalloy, 79HMA, PCS) 1J85 yog cov nickel-hlau sib nqus alloy, muaj li ntawm 80% npib tsib xee thiab 20% hlau cov ntsiab lus. Tsim nyob rau hauv 1914 los ntawm physicist Gustav Elmen.

Nws yog ib qho tseem ceeb rau nws cov magnetic 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 nyob rau hauv cov hlau nplaum tiv thaiv 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 nrog rau qhov siab permeability, nws lwm yam khoom sib nqus yog cov coercivity qis, 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 qhov kev ntxhov siab tsis sib xws 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.

1J85 yog dav siv nyob rau hauv xov tooj cua-electronic kev lag luam, precision instruments, chaw taws teeb tswj thiab tsis siv neeg tswj system.
