Khoom Description
Lub li-hu ua hlau-nickel alloy, raws li lub npe qhia, ib qho ntawm nws cov khoom tseem ceeb yog npib tsib xee. Feem ntau, cov ntsiab lus nickel ntawm hlau-nickel alloy yog nyob rau hauv thaj tsam ntawm 30%-90%. Qhov kev ua tau zoo ntawm cov hlau-nickel alloy yog nyob rau hauv nws cov magnetic permeability siab, tshwj xeeb tshaj yog nyob rau hauv cov tsis muaj zog thiab nruab nrab magnetic teb. Tsis tas li ntawd, vim qhov sib ntxiv ntawm cov hlau zoo nkauj npib tsib xee, lub zog quab yuam ntawm cov hlau -nickel alloy yog me me, kev ua tau zoo heev, thiab nws muaj peev xwm tiv thaiv xeb zoo dua piv nrog lwm cov alloys. Tsis tas li ntawd, hlau thiab npib tsib xee alloys tuaj yeem tau txais cov khoom sib nqus zoo heev yog tias lawv tau ua tiav tshwj xeeb. Tab sis cov alloy kuj muaj qhov tsis zoo ntawm kev ua lag luam kim. Vim tias nws muaj cov ntsiab lus xws li npib tsib xee thiab cobalt, tus nqi ntawm cov hlau no feem ntau siab dua, thiab cov khoom siv thinner, nws kim dua.
