Ua ntej, cov hlau ntshiab muaj cov khoom sib nqus zoo heev. Nws nthuav tawm cov permeability siab thiab qis hysteresis poob, ua rau nws zoo tagnrho rau kev siv hluav taws xob thiab hluav taws xob xws li transformers, inductors, thiab lwm yam khoom sib nqus. Cov khoom no tso cai rau cov hlau ntshiab kom xa tau zoo thiab tswj cov chaw sib nqus, uas yog qhov tseem ceeb hauv ntau lub tshuab hluav taws xob.
Qhov thib ob, cov hlau ntshiab yog cov tiv taus corrosion hauv qee qhov chaw, tshwj xeeb tshaj yog thaum nws raug kho kom zoo lossis alloyed nrog lwm cov hlau los ua cov hlau tsis muaj steel. Thaum cov hlau ntshiab nws tus kheej yuav tsis zoo li corrosion-resistant li stainless hlau, nws tus cwj pwm corrosion tuaj yeem tswj tau los ntawm kev kho kom zoo thiab txheej txheej, ua rau nws tsim nyog siv rau ntau yam kev mob.
Tsis tas li ntawd, cov hlau ntshiab muaj qhov zoo ductility thiab malleability. Qhov no txhais tau hais tias nws tuaj yeem ua tau yooj yim zoo li tus thiab tsim rau ntau yam duab thiab ntau thiab tsawg, ua rau nws muaj ntau yam siv rau hauv kev tsim cov txheej txheem xws li casting, forging, thiab vuam. Qhov kev ua tau yooj yim no tso cai rau cov hlau ntshiab kom haum raws li cov kev xav tau tshwj xeeb ntawm cov ntawv thov sib txawv.
Tsis tas li ntawd, cov hlau ntshiab kuj tseem pheej yig dua piv rau lwm cov hlau thiab alloys. Nws cov kev nplua nuj nyob hauv cov khoom siv ntuj tsim thiab tsim cov txheej txheem refining pab txhawb rau nws cov nqi-zoo, ua rau nws yog ib qho kev xaiv txaus nyiam rau kev lag luam siv uas tus nqi yog qhov tseem ceeb rau kev txiav txim siab.
Thaum kawg, hlau ntshiab yog ib puag ncig tus phooj ywg. Nws tsis muaj tshuaj lom thiab tsis tso tawm cov pa phem thaum lub sijhawm tsim khoom lossis siv. Qhov no ua rau nws yog qhov kev xaiv tsim nyog rau cov ntawv thov uas ib puag ncig cuam tshuam yog kev txhawj xeeb.
