alloy ntawm txhuas uas yog 4 feem pua tooj liab thiab muaj cov magnesium me me, manganese, hlau, thiab silicon: siv rau cov ntawv thov xav tau lub teeb thiab lub zog, xws li hauv kev tsim dav hlau.
Duralumin yog dab tsi?
Duralumin, muaj zog, nyuaj, lub teeb hnyav ntawm txhuas, dav siv hauv kev tsim dav hlau, nrhiav pom hauv 1906 thiab patented hauv 1909 los ntawm Alfred Wilm, German metallurgist; nws yog Ameslikas tsim tsuas yog nyob rau hauv lub tuam txhab Dürener Metallwerke ntawm Düren, lub teb chaws Yelemees. (Lub npe yog kev cog lus ntawm Dürener thiab txhuas.)
Cov hlau twg tsis muaj duralumin?
Cov nplooj ntawv no hu ua alclad, thiab tau siv dav los ntawm kev lag luam aviation. Yog li, peb tuaj yeem hais tias duralumin muaj tooj liab (Cu), magnesium (Mg) thiab manganese (Mn) tab sis tsis muaj sodium (Na).
Puas duralumin kim?
Duralumin lossis Duraluminium yog Aluminium-alloy, nyob rau hauv qhov chaw tseem ceeb yog tooj liab, manganese, thiab magnesium. Nws yog qhov lightest thiab kim tshaj plaws ntawm tag nrho cov hlau xaiv rau Mengane.
Cov hlau twg muaj nyob hauv German nyiaj?
German Silver yog ib qho hlau ntawm tooj liab, zinc thiab npib tsib xee, qee zaum kuj muaj cov txhuas thiab tin. Nws yog Ameslikas lub npe rau nws cov xim nyiaj-dawb, tab sis lub sij hawm 'nyiaj' yog tam sim no txwv tsis pub alloys tsis muaj cov hlau.
