Siab heev pib permeability thiab siab tshaj permeability (core kom zoo dua)
Qhov tseem ceeb ntawm Permalloy yog nyob rau hauv nws cov permeability siab heev. Ua tsaug rau qhov tseeb muaj pes tsawg leeg ntawm kwv yees li 79% npib tsib xee thiab li 4% molybdenum, nrog rau kev tswj hwm crystalline kev ntxhib los mos, nws qhov pib permeability (μᵢ) tuaj yeem ncav cuag 20,000-50,000, thiab qhov siab tshaj plaws permeability (μmax) tuaj yeem ncav cuag 200,000-500,000 limecon steel siab tshaj li ntawm max. ≈ 50,000) thiab ferrites (μmax ≈ 10,000-20,000). Nyob rau hauv qhov tsis muaj zog hlau nplaum (xws li qib ntawm lub ntiaj teb magnetic teb), Permalloy muab cov lus teb zoo heev, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv xws li kev tiv thaiv kev sib nqus thiab cov teeb liab tsis muaj zog. Piv rau lwm cov qib high-permeability (piv txwv li, 1J85), 1J79 muaj cov kab dav dav dua thiab cov yam ntxwv kub ruaj khov dua.
Tsis tshua muaj coercivity thiab hysteresis poob
Ua tsaug rau nws cov purity siab thiab optimized crystalline kev ntxhib los mos, Permalloy muaj tsis tshua muaj coercivity (Hc tsawg tshaj li los yog sib npaug rau 10 A / m), ib tug me me hysteresis voj cheeb tsam, thiab hysteresis poob qis dua piv rau zoo tib yam silicon steel thiab ferrites. Nyob rau hauv alternating magnetic teb, nws cov tub ntxhais poob kev ua tau zoo heev, ua rau nws tsim nyog rau daim ntaub ntawv uas yuav tsum nruj me ntsis rau cov teeb liab fidelity thiab efficiency xws li suab transformers (20Hz-20kHz), precision tam sim no transformers, thiab magnetic amplifiers. Nws lub voj hysteresis nqaim heev ua kom muaj kev ncaj ncees sib kis ntawm cov teeb liab tsis muaj zog nrog kev cuam tshuam tsawg.
Ntau dua resistivity rau eddy tam sim no poob tswj
Qhov kev tiv thaiv ntawm permalloy yog kwv yees li 0.55-0.60 μΩ·m, siab dua li ntawm cov hlau silicon zoo tib yam (li 0.25-0.30 μΩ·m). Qhov sib ntxiv ntawm molybdenum ua tau zoo ua kom cov hlau tsis muaj zog, txo qhov poob tam sim no, thiab txhim kho nws cov kev ua haujlwm tseem ceeb hauv nruab nrab thiab siab - siv zaus. Cov cuab yeej no ua rau nws tsim nyog rau cov xwm txheej uas yuav tsum tau ua nruj me ntsis ntawm kev ua haujlwm thiab qhov kub thiab txias, xws li siab - zaus transformers, radar systems, thiab aviation fais fab mov (400Hz). Muab piv rau cov ntshiab nickel-hlau alloys (piv txwv li, 1J50), 1J79 nthuav tawm cov kev ua haujlwm siab tshaj plaws vim muaj qhov sib ntxiv ntawm molybdenum, tso cai rau nws cov zaus ua haujlwm tau nce 2-3 zaug.
Zoo machining thiab tsim cov khoom
Permalloy tuaj yeem ua haujlwm kub thiab txias ua haujlwm zoo, tso cai rau nws los ua forged, dov, thiab stamped rau hauv ntau yam duab. Nws cov ductility tshaj li cov hlau nplaum ferrite feem ntau, ua rau nws tsim nyog rau kev tsim cov laminated cores, sib nqus shields, thiab precision stampings. Nws tuaj yeem muab dov rau hauv cov strips nyias heev (thickness mus txog 0.01-0.05 mm), zoo tagnrho rau cov ntawv thov ntau zaus. Annealing optimizes magnetic zog los ntawm relieving kev nyuaj siab, restores permeability, thiab txo coercivity. Pa machining cov haujlwm xws li tig, milling, drilling, thiab sib tsoo yog siv tau; pom zoo siv cov cuab yeej siv tawv hlau txiav.
Zoo heev magnetic shielding kev ua tau zoo
Permalloy lub siab permeability thiab qis coercivity muab nws tshwj xeeb zoo nyob rau hauv daim ntawv thov sib nqus shielding. Nyob rau hauv ncaj qha tam sim no thiab qis - zaus alternating magnetic teb, Permalloy tuaj yeem nqus tau zoo thiab coj cov kab sib nqus flux, muab kev tiv thaiv zoo heev. Nws qhov kev tiv thaiv kev ua tau zoo yog qhov zoo tshaj plaws ntawm cov hlau silicon hlau thiab ferrites zoo tib yam, ua rau nws tsim nyog rau cov ntawv thov nrog cov kev cai nruj heev rau qhov chaw sib nqus, xws li cov cuab yeej precision, electron microscopes, quantum sensors, thiab MRI hlau nplaum.
