Yog vim li cas vim li cas lub aluminium sawb yuav siv tau raws li ib tug hollow iav hollow spacer yog hais tias nws yog thaum kawg txawv los ntawm ib tug series ntawm cov ntaub ntawv hlau. Yog li cas yog vim li cas?
Lub ntom ntawm aluminium yog me me, tsuas 2.7g / cm. Txawm hais tias nws yog mos, nws tau ua ntau yam txhuas aluminium xws li tawv aluminium, super-hard aluminium, xeb-proof, txhuas casting thiab cov zoo li.Aluminium muaj zoo ductility kom nws tau yob ntau txhuas khoom xws li txhuas hlau thiab txhuas strips.Tus deg ntawm txhuas yog resistant rau corrosion vim nws ntom oxide tiv cov zaj duab xis. Aluminium muaj silvery dawb luster thiab tseem corrosion resistant. Aluminium kuj muaj zoo reflection zog rau lub teeb.The reflected ultraviolet teeb yog muaj zog tshaj nyiaj, thiab lub purer aluminium, zoo dua tus peev xwm xav tau.Aluminium muaj suab absorbing zog thiab suab teebmeem zoo, yog li aluminium kuj siv hauv chav broadcasting thiab ceilings nyob rau hauv niaj hnub loj-scale architectural chav.Low kub tsis kam, aluminium ntawm tsawg kub, nws lub zog yog nce tsis brittleness, yog li nws yog zoo tagnrho rau cov khoom siv cryogenic.
Cov kev zoo ntawm txhuas ua txhuas tej daim kab xev raws li txhuas khoom muaj peev xwm tuav tau hollow aluminium spacers.
