Aluminium yog ib qho khoom siv.
Ntshiab aluminium yog cov hlau mos heev nrog cov hlau qis, tab sis tau kawg, tag nrho cov txhuas (txawm tias cov alloys) muaj tib lub modulus los yog nruj, tsuas yog sib txawv zog.
Ib qho alloy tsuas yog sib xyaw ntawm cov hlau feem ntau nrog ob peb yam tshwj xeeb ntxiv uas tuaj yeem tsim cov txiaj ntsig zoo. Qee qhov ntawm cov hlau no tuaj yeem ua kom tawv tawv zoo dua li lwm tus, qee qhov muaj kev tiv thaiv corrosion ntau dua, thiab lwm yam. Txhua qhov txhuas alloys feem ntau yog txhuas, tsuas yog qee qhov tuaj yeem kho cua sov thiab qee qhov tuaj yeem ruaj ntseg welded.
Muaj ntau txoj hauv kev los ntxiv dag zog rau cov hlau, thiab qhov ua kom yuam kev yog ua kom tsis txhob ua rau nws tawg. Ib txoj hauv kev yog kev ua haujlwm txias lossis deform cov hlau, xws li cov ntawv ci lossis cov hlau uas tsim los ntawm cov tuab tuab, raws li cov tawv tawv tawv, cov txiaj ntsig yuav nce ntxiv. Qhov no txhais tau hais tias lub load uas koj yuav tsum tau thov mus ntxiv deform cov hlau yog nyob rau theem kawg yam tsis tau rov qab mus rau lub yield load! Yog lawm, hlau feem ntau yog "muaj zog tshaj" (aka feem ntau tsim tau) ua ntej nws tawg!
